Aluminium Powdered aluminium and rust in the approximate ratio of 1:3 are packed in a refractory crucible with a magnesium ribbon, or a powder of magnesium and barium peroxide, to ignite it. Aluminium can be protected by a thick layer of oxide made by electrolysis, a process called "anodizing." The surface is first thoroughly cleaned and degreased in trichloroethylene, or by electrolysis, where the aluminium is the cathode and the grease driven off by the evolved hydrogen. Aluminium sulphate is found in nature as the rare mineral Kalinite, which is soluble in water, so it is found only near volcanoes and such places where it is make by the action of sulphuric acid on clays, such as on Lipari, near Vesuvius, and a few places in Germany and South America. www.du.edu /~jcalvert/phys/alumin.htm   (4695 words)

Aluminium oxide - Wikipedia, the free encyclopedia Aluminium oxide is responsible for metallic aluminium's resistance to weathering. Metallic aluminium is very reactive with atmospheric oxygen, and a thin passivation layer of aluminium oxide quickly forms on any exposed aluminium surface. Aluminium oxide, also known as alumina, is the main component of bauxite, the principal ore of aluminium. en.wikipedia.org /wiki/Aluminium_oxide   (536 words)

Encyclopedia   (Site not responding. Last check: 2007-10-26) Aluminium hydroxide is used as an antacid and as a phosphate binder in the management of chronic renal failure. Aluminium poisoning in these circumstances may be enhanced by the administration of oral aluminium hydroxide as a phosphate binder. Aluminium toxicity should be considered in those who are exposed occupationally to aluminium dust and who develop respiratory or neuro- psychiatric symptoms, and in patients with renal failure who may be at risk of aluminium retention. www.eamg-med.com /members/encyclopedia/8/8_3/8_3_6.shtml   (9807 words)

Integrated process for treatment of residual solutions from anodization plants - Patent 4265863 Furthermore, the aluminium sulphate of the anodization bath is precipitated in the form of ammonium alum or potassium alum by the addition of ammonium sulphate or potassium sulphate. This provides both a hydrated aluminium sulphate, for which there are major outlets in the paper industry and the treatment of waste water, for example, and a concentrated solution of sulphuric acid which has not been contaminated by new reagents and which is thus capable of being recycled to the anodization stage. Thus the sodium sulphate still present will, in the end, undergo crystallization, while the extraneous ions will be adsorbed by the aluminium hydroxide and finally pass to the third of the sets of operations, and to the first, if this takes place, thus entering the sodium aluminate and aluminium sulphate, respectively, which are produced therein. www.freepatentsonline.com /4265863.html   (5127 words)

Fax: 9562243 Attn: PROF. K. M. A. MUNIM However, aluminium is the third most common element in the Earth's crust and this fact alone has made it acceptable and is used to forward the claim that aluminium salts cannot pose an environmental hazard. aluminium sulphate in the treatment of arsenic-contaminated groundwater is of concern as exposure to aluminium from water sources is far more common than has been acknowledged. Aluminium is mainly present in unprocessed foods as a relatively insoluble aluminosilicate, or else associated with chemicals such as tannin which form complexes which are very resistant to digestion. phys4.harvard.edu /~wilson/arsenic/countries/bangladesh/mortoza/ARTICLE5.html   (1830 words)

ALFED : The Aluminium Federation - Position Paper 2 - Aluminium and Health Because aluminium is such a commonly occurring element, even in the dust in the air, accurate detection and analysis of aluminium in samples is notoriously difficult because of contamination of the samples. The early claims of aluminium being associated with deposits in the brain sections of Alzheimer's disease victims were proved to be due to contamination of the samples during preparation, leading to an erroneous picture about the role of aluminium. The aluminium industry around the world is working with government research agencies and the relevant medical research organisations and charities, to ensure that high quality research is supported and that the public is provided with a fair and balanced account of this complex issue. www.alfed.org.uk /content/default.asp?PageId=110   (2030 words)

Alzheimer's Society Factsheet - Aluminium and Alzheimer's disease The 'aluminium hypothesis' was first put forward in 1965 when it was shown that the injection of aluminium compounds into rabbits caused tangle-like formations in nerve cells. Aluminium has been shown to be associated with both plaques and tangles in the Alzheimer brain. Only a minute proportion of the aluminium we ingest from these various sources is absorbed by the body, and even this small fraction is usually excreted in the urine or harmlessly deposited in bone which acts as a 'sink' to remove aluminium. www.alzheimers.org.uk /Facts_about_dementia/Risk_factors/info_aluminium.htm   (1057 words)

Aluminium sulfate - Wikipedia, the free encyclopedia Aluminium sulfate is a widely used industrial chemical. It is frequently used as a coagulant in the purification of drinking water and waste water treatment plants, and also in paper manufacturing. Aluminium sulfate is rarely, if ever, encountered as the anhydrous salt. en.wikipedia.org /wiki/Aluminum_sulfate   (300 words)

Aluminum sulfate (UK PID) Uraemic patients on long-term haemodialysis may have an increased aluminium load via intravenous exposure to high concentrations of aluminium sulphate in dialysis (usually tap) water (Ward et al, 1978; Alfrey, 1980), although this should now be avoidable by deionization or reverse osmosis of the water prior to use. Desferrioxamine and aluminium bone disease In 32 patients desferrioxamine therapy controlled progression of dialysis-associated aluminium osteodystrophy with bone scans in 21 cases reverting to normal or showing a pattern typical of hyperparathyroidism (Botella et al, 1984). The aluminium content of cow's milk and soy milk are considerably higher (10-20 and 100 fold respectively) than human breast milk which has an aluminium concentration of 5-20 µg/L and this may contribute to aluminium intoxication in premature infants with renal failure (Bishop et al, 1989). www.intox.org /databank/documents/chemical/alumsulf/ukpid34.htm   (7047 words)

Aluminium in drinking water. A health report on drinking water treatment linking Alzheimer's mental health disease in ... While some scientists believe that the aluminium deposits are only a side effect of Alzheimer's, a growing number of investigators say that aluminium may play a central role in causing the disease that afflicts mostly elderly people. Aluminium occurs naturally in some waters but is also introduced as aluminium sulphate by some municipal water departments to remove fine particles, colour and bacteria. The reason: municipalities in Canada and other countries often use aluminium sulphate, or alum, to remove mineral particles from water in filtration plants, a process that leaves an aluminium residue in the water. www.doulton.ca /alum1.html   (610 words)

Aluminium and Alzheimer's disease Aluminium was identified as the cause of ‘dialysis dementia’. There is some evidence that aluminium, which is not a highly reactive metal like iron or copper, may interfere with this process, possibly allowing more free iron to circulate and so generate more free radicals which in turn generate yet more free radicals in a chain reaction. Aluminium concentrations are 10 to 20 times greater in most cow's milk formulas (and 100 times greater in soya-based formulas) than in breast milk. www.alzscot.org /pages/info/aluminium.htm   (2211 words)

ALUMINIUM Aluminium, the third most common element onEarth after oxygen and silicon, and by far the most abundant metal on Earth, is now used very widely for everything from soft drink cans to car bodies to window frames. Aluminium is one of a number of soft and weak metals (like copper and tin) that scientists call "poor" metals. To refine this to aluminium, the alumina has to be dissolved and the aluminium recovered by electrical means. www.atlanticeurope.com /Elements/Aluminium.html   (709 words)

An Experiment to further investigate Crystal structures I chose copper sulphate because it is cheap and forms crystals readily but I also used one of the aluminium double salts because of the complex shapes they formed compared to the simple salt crystal structures. With the potassium aluminium sulphate there was some gas given off at the electrode connected to the positive terminal and approximately twice as much gas from the other electrode. The electric current passing through the copper sulphate solution made some of the copper sulphate split up and there was a thin layer of copper on the electrode attached to the negative terminal of the power supply, this means that the copper ions were positively charged. www.sci-journal.org /reports/vol4no1/v4n1a2.html   (1351 words)

No adverse effects of aluminium in vaccines Aluminium salts (potassium aluminium sulphate, aluminium sulphate, or aluminium hydroxide) have been used for decades in vaccine formulations as adjuvants (non-specific stimulators of the immune response), and in this role they are vital to the protective efficacy of vaccines. But aluminium has been blamed for side-effects in vaccine recipients, such as local reactions at the site of vaccination and a chronic progressive syndrome called macrophagic myofasciitis. However, replacing aluminium with another adjuvant would be a massive undertaking because all such vaccines would have to be tested in clinical trials and relicensed; besides, no obvious replacement is available. www.eurekalert.org /pub_releases/2004-01/l-nae012804.php   (273 words)

Aluminum Aluminium sulphate is widely used as a coagulant in drinking water treatment. The determination of aluminium (residual alum) is usually required for the control of alum coagulation and filtration processes at water works. Aluminium salts are found in natural waters; levels are reported to be increasing particularly in areas affected by acid rain. www.aquaticlife.ca /Parameters/aluminium.asp   (96 words)

CSIRO - Aluminium Study Puts Drinking Water In The Clear However some conflicting evidence in earlier studies suggested that aluminium that is left in treated drinking water may be more readily taken up by the body than aluminium from other sources. Most of the aluminium we consume in our food and drinking water is not absorbed and goes straight through our bodies to be excreted in faeces. A technique normally used for measuring trace minerals in environmental samples, was adapted to measure the amount of aluminium in blood and urine. www.csiro.au /files/mediaRelease/mr1998/AluminiumStudyPutsDrinkingWater.htm   (783 words)

Aluminium in Antiquity   (Site not responding. Last check: 2007-10-26) Naturally occurring compounds of aluminium were used by numerous civilisations for various reasons. Clays consisting of hydrated aluminium silicates were used in pottery and aluminium sulphate (alum) was known to the Egyptians, Greeks and Romans for its use as a mordant in the dyeing process. Aluminium was then a rare and precious metal and less important guests had to eat from plates of pure gold. www.world-aluminium.org /history/antiquity.html   (287 words)

Sulphate Sulphates are introduced into treated waters by the use of such chemicals as aluminium sulphate, sodium bisulphate (dry acid) and sulphuric acid. In industrial waters containing sulphate localized corrosion of iron, steel and aluminium in plant and pipework can occur through the action of sulphate-reducing bacteria. High sulphate levels can also cause damage to concrete and cement based materials through the formulation of calcium solphoaluminate. www.aquaticlife.ca /Parameters/Sulphate.asp   (149 words)

Mortoza_fact_sheets These chelates are one of the most dangerous routes of infiltration into the body for aluminium, and wherever special circumstances, such as this arise, it is highly dangerous to use aluminium for cooking utensils. Aluminium sulphate is no longer recommended because of the neurological affect of aluminium poisoning. The original assumption that aluminium sulphate could be used for arsenic reduction because the people are familiar with its use is no longer valid as aluminium is now recognised to be causing neurological problem. phys4.harvard.edu /~wilson/arsenic/countries/bangladesh/fact_sheets.html   (8157 words)

Disturbance of cerebral function in people exposed to drinking water contaminated with aluminium sulphate: ... Objective To establish whether people exposed to drinking water contaminated with 20 tonnes of aluminium sulphate in the Camelford area of Cornwall in the south west of England in July 1988 had suffered organic brain damage as opposed to psychological trauma only. On 6 July 1988, 20 tonnes of aluminium sulphate were accidentally emptied into the treated water reservoir that served 20 000 people in the Camelford area of Cornwall. In such patients the initial epidemic of aluminium related diseases was due to contamination of the water used to prepare dialysate,[7] and later the importance of gastrointestinal absorption was also established.[8-10] Subsequent lowering of aluminium exposure has led to the near disappearance of the florid forms of aluminium induced disease. www.findarticles.com /p/articles/mi_m0999/is_7213_319/ai_56210119   (783 words)
