Webphosphorite, also called phosphate rock, rock with a high concentration of phosphates in nodular or compact masses. The phosphates may be derived from a variety of sources, … WebFeb 24, 2010 · Interaction of phosphate with the surfaces of clays and metal oxyhydroxides is important for nutrient cycling in natural and agricultural systems. We examined the specific adsorption of phosphate to boehmite (γ-AlOOH) by solid-state 31P NMR spectroscopy, which yields evidence for the presence of two bridging bidentate surface …

WebApr 21, 2024 · Arsenic is an inorganic pollutant that, depending on oxidation–reduction and pH level conditions, may be found in natural waters in two variants: As(III) and As(V). Any treatment to effectively remove arsenic from water will be conditioned by the presence of one or both variants. In this context, this study assesses using electrochemically … WebMar 22, 2024 · The aqueous speciation of these trace elements appeared to be dominated by inorganic species (i.e., non-DOM-bound), namely monovalent cations for Li and Rb, oxyanionic species for V and Se, and carbonate and phosphate complexes for Ce and Gd , although aqueous complexes with Cl and SO 4 were also present for other trace elements. … tapasya spices order form
