	Trisodium phosphate - Biocrawler (Site not responding. Last check: 2007-11-07)
		Trisodium phosphate, available at most hardware stores in white powder form, is a cleaning agent and degreaser, commonly used to prepare surfaces for painting (household), sold as 'TSP'.
		Similar chemicals were once common in laundry and dishwashing detergents, but the phosphate, being a fertilizer, would cause algal blooms in the bodies of water that the drains led to.
		A mixture of monosodium phosphate and trisodium phosphate is used as a phosphate buffer: [1] (http://members.nuvox.net/~on.jwclymer/phos.html)

		In inorganic chemistry, a phosphate is a salt of phosphoric acid.
		In agriculture phosphate refers to one of the three primary plant nutrients, and it is a component of fertilizers.
		Runoff of phosphates from excessively fertilized farmland can be a cause of phosphate pollution in surface waters, leading to eutrophication (algal bloom) and consequent oxygen deficit (anoxia) for fish and other aquatic life in the same manner as phosphate-based detergents.

	Glossary : Phosphate
		The complex phosphates also are a group of sequestering agents widely used in detergent formulations (except where phosphates are banned by law) because of their superiority in chemical water softening, sequestering, and other builder functions.
		This is caused by the increasing concentration of phosphate as pure water permeates the membrane, and the tendency for the pH to increase on the concentrate side of the RO membrane as the salts become more concentrated.
		Phosphates can always be removed by coagulation with alum (aluminum sulfate) or ferric chloride to form insoluble aluminum phosphate or iron phosphate floc particles, which are then captured with a sediment filter.

		A JavaScript that calculates the amount of monosodium phosphate and trisodium phosphate necessary to achieve a buffer at a given pH and buffer strength.
		The buffer may be made by adding 0.082 g anhydrous monosodium phosphate and 0.12 g trisodium phosphate dodecahydrate to 100 ml water.
		Trisodium Phosphate = [PO Using the molecular weights for anhydrous monosodium phosphate and trisodium phosphate dodecahydrate (the typical lab forms) together with the buffer strength, the actual percentages are calculated.

	Trisodium phosphate - Wikipedia, the free encyclopedia
		Trisodium phosphate (TSP), available at most hardware stores in white powder form, is a cleaning agent and degreaser, commonly used to prepare household surfaces for painting.
		However it should not be confused with the related compounds sodium dihydrogen phosphate, also known as monosodium phosphate or MSP, and disodium hydrogen phosphate.
		Similar chemicals were once common in laundry and dishwashing detergents, but the phosphate, being a fertilizer, would cause algal blooms in the bodies of water that the drains led to.

	Production of phosphates from alkali-processes phosphate rock - Patent 4777026
		The desired phosphates include di- and mono-sodium orthophosphate; pentasodium tripolyphosphate; sodium metaphosphate and its polymers; tetrasodium pyrophosphate; ammonium phosphate; sodium ammonium hydrogen phosphate, magnesium ammonium phosphate; and the corresponding potassium salts thereof.
		Process according to claim 1, in which the desired phosphates are chosen from the group consisting of di-and mono- sodium orthophosphates, pentasodium tripolyphosphate, sodium metaphosphate and its polymers, tetrasodium pyrophosphate, sodium ammonium hydrogen phosphate, and corresponding potassium salts thereof; and ammonium phosphates and magnesium ammonium phosphate.
		A precipitate of magnesium ammonium phosphate was formed, with the pH being controlled at 8 by additions of ammonia and carbon dioxide to avoid precipitation of magnesium phosphates at high pH, and to maintain magnesium bicarbonate in solution by the presence of ammonia.

	phosphate. The Columbia Encyclopedia, Sixth Edition. 2001-05
		Since calcium phosphate is only slightly soluble in water, it is not very suitable as a source of the phosphorus necessary for plant life; however, by treating it with sulfuric acid the soluble calcium acid phosphate known as superphosphate of lime is formed.
		Other important inorganic phosphates include ammonium phosphate, important as a fertilizer; trisodium phosphate, used in detergents and for softening water; and disodium phosphate, used to some extent in medicine and in preparing baking powders.
		Nucleotides are phosphate esters that play an important role in the conservation and use of the energy released in the metabolism of foods in the body; adenosine triphosphate is an important nucleotide.

		Trisodium phosphate, or TSP, is available to consumers in hardware and home improvement stores in the form of white crystals or powder.
		Additionally, due to the high pH and phosphate content of TSP solutions, residues from outdoor use should be captured to prevent contaminating surface water or storm drains with the runoff.
		Phosphates including TSP are common additives in dish and laundry detergents, serving as "builders" to help soften water and prevent scale buildup.

	Enhanced Phosphate Treatment for Drum-Recirculating Boilers
		While phosphate had the ability to significantly curtail incidents of caustic embrittlement and caustic gouging damage, it could not totally remove the fear of having free hydroxide in excess of that associated with trisodium phosphate.
		Forcing a boiler to operate with phosphate concentrations in excess of its equilibrium value means that any changes in the heat and mass transfer patterns in the high heat flux zone may result in corresponding changes in Na/PO ratios and the rates of precipitation and hydrolysis.
		Phosphate is also known to affect crystalline structure of the adherent magnetite and may possibly alter its protective properties.

	NTP: Abstract for TR-294 - Chlorinated Trisodium Phosphate
		Two-year studies were begun in male and female F344/N rats at doses of 0, 500, 1,000, or 2,000 mg/kg of chlorinated trisodium phosphate in water by gavage (10 ml/kg).
		The lower survival and mean body weights of the dosed female mice may have been due to a greater incidence of uterine/ovarian infections in these mice rather than to a direct toxic effect of chlorinated trisodium phosphate.
		Chlorinated trisodium phosphate was weakly mutagenic in strain TA1535 of Salmonella typhimurium in the presence of Aroclor 1254-induced male Sprague-Dawley rat or male Syrian hamster liver S9.

	Detergent Chemistry: Builders & Additives
		Trisodium phosphate is little used these days, because phosphates cause eutrophication of water.
		If a piece of cloth has imbedded in it some calcium in the form of an insoluble calcium soap, the phosphate molecule re-dissolves the calcium, releases sodium which re-combines with the soap molecule, and thereby regenerates useable soap.
		Phosphate have become out of favour biologically because of eutrophication, but suitable alternatives are hard to find that will completely replace them.

	Removal of Lead Contaminated Dusts from Hard Surfaces
		Government guidelines have widely recommended trisodium phosphate (TSP) or "lead-specific" cleaning detergents for removal of lead-contaminated dust (LCD) from hard surfaces, such as floors and window areas.
		The purpose of this study was to determine if low-phosphate, non-lead-specific cleaners could be used to efficiently remove LCD from 3 types of surfaces (vinyl flooring, wood, and wallpaper).
		Laboratory methods were developed and validated for simulating the doping, embedding, and sponge cleaning of the 3 surface types with 4 categories of cleaners: lead-specific detergents, nonionic cleaners, anionic cleaners, and trisodium phosphate (TSP).
