In order to combine the properties of phosphate surfactants and silicone surfactants, the polyether-modified polysiloxane phosphate (PPSP) was prepared. Firstly, the intermediate was synthesized throu...
In order to avoid using P2O5 as phosphorylation reagent in phosphorylation reaction, an amphoteric phosphate ester surfactant was synthesized by using polyphosphate acid as phosphorylation reagent. Th...
In this study, the natural and modified palygorskites were tested to remove phosphate ions from aqueous solution. The modified palygorskites were prepared by being activated with hydrochloric acid an...
Abstract: Competitive adsorption between glyphosate and phosphate on goethite was evaluated. The influence of background electrolyte on the adsorption of glyphosate and phosphate was also investigated...
Abstract: The effect of phosphate on the formation of Fe oxides from Fe(II) salts is important because phosphate is a ubiquitous anion in natural environments. For this reason, the products formed by ...
Bederite, ideally Ca Mn Fe Mn (PO ) (H O) , orthorhombic, a = 12.559(2), b = 12.834(1), c= 11.714(2) ?, V = 1887.8(4) ? , Z = 4, space group Pcab, is a new mineral from the El Pe?(R)AE pegmatite, Ne...
Abstract: Because layered Fe(II)Fe(III)-hydroxides (Green rusts, GRs) are anion exchangers, they represent potential orthophosphate sorbents in anoxic soils and sediments. To evaluate this possibility...
Abstract: We investigated the crystallization of ferrihydrite prepared by hydrolysis of Fe(NO3)3 solutions containing phosphate. Crystallization was studied at different pH (3–9), temperatures (298, 3...
Laboratory growth experiments were conducted to investigate the oxygen isotope effects associated with bacterial metabolism of phosphatic compounds commonly available in nature. The observed oxygen is...
Phosphovanadylite, whose simplified formula is (Ba,Ca,K,Na)x[(V,Al)4P2(O,OH)16]·12H2O, is a new vanadium phosphate zeolite mineral found in the Phosphoria Formation at Monsanto’s Enoch Valley Mine, So...

Abstract: The formation and structure of hematite aggregates were examined by dynamic and static light scattering techniques. A large range in coagulation kinetics was studied by varying either indiff...
The nature and number of acid sites per unit weight on a series of materials obtained by interaction of a montmorillonite with zirconium or cerium hydrogenphosphates precipitated in situ by reaction b...
The decomposition of kaolinite by treatment with trimethyl phosphate (TMP) and the composition of the new crystalline phase formed were studied. On hot treatment with TMP, kaolinite forms a crystallin...
Abstract: Although phosphate sorption by goethite and other less-abundant Fe oxides strongly influences the concentration of this anion in the soil solution and aquatic environments, relatively little...
