	Title page for ETD etd-10032003-114015
		Phosphate was sorbed in single-mineral aqueous suspensions of ferrihydrite (ferric hydroxide), boehmite (aluminum oxyhydroxide), goethite (iron oxyhydroxide), or non-crystalline (non-xl) Al-hydroxide, and mixtures of ferrihydrite/boehmite, goethite/boehmite, and ferrihydrite/non-xl Al-hydroxide at pH 6.
		Phosphorus K-XANES spectra for phosphate on Fe- vs. Al-oxide minerals differed in that a weak doublet peak was observed for Fe-oxides on the low-energy side of the P K-edge, i.e., in the pre-edge region.
		The quantitative distribution of phosphate between ferrihydrite and boehmite in mixtures of these minerals was determined using linear combination fitting (LCF) analysis of the XANES pre-edge region.

		) in glycol at elevated temperatures yielded the glycol derivative of boehmite together with a small amount of well-crystallized boehmite and a residue of unreacted gibbsite.
		The addition of water to the medium increased the reactivity of gibbsite and yielded a novel phase having a large basal spacing.
		XRD analysis showed that the products had the boehmite layer structure and that the difference between the basal spacings of the present products and those of the corresponding glycol derivatives of boehmite obtained in pure glycols was about the same as the thickness of a boehmite layer.

		Adsorption behavior of indicator molecules on cationically modified colloidal boehmite from aqueous solution was compared to indicator adsorption on naturally cationic, unmodified colloidal boehmite.
		Three types of anionic dyes commonly used in printing inks were used as indicators; C.I. Acid Blue 9, Acid Red 37, and Direct Yellow 50.
		Waterfastness testing on coated paper indicates cationic modification of pigments used in ink receiver formulations is an effective way to improve waterfastness of images printed with anionic dye colorants.
