Evaluating Steel Byproducts and Natural Minerals for Phosphate Adsorption from Agricultural Subsurface Drainage
… to the loss of P from soils. The use of adsorption materials to bind P has emerged as a promising technology for P removal. The objective of this study was to perform batch and column experiments to investigate the P adsorption potential of several materials for agricultural subsurface …

Preparation and characterization of cross-linked chitosan beads for phosphate adsorption in aqueous solution
… chemical functionalities that affect the adsorption properties. The general features of the adsorption and textural properties of the bead systems were studied using model dye compounds such as p-nitrophenolate (PNP) and phenolphthalein (PHP). The results from the uptake study of the model …

PHOSPHATE ADSORPTION AND DESORPTION ON TWO CONTRASTING SOILS USED FOR LAND TREATMENT OF WASTEWATER
… treated wastewater. This research examines the phosphate adsorption - desorption behavior of two soils: Charlton silt loam, a typical acid soil from New England which is being used in experimental wastewater treatment, and Tujunga coarse sandy loam from a wastewater land treatment facility …

Effectiveness of Non-Chromate Inhibitors on Preventing Corrosion of Aluminum Alloys
Because it is known that the adsorption of ions on a metal affects the corrosion resistance of that metal, ion adsorption on aluminum is an important issue. In this study, the adsorption/accumulation of proposed inhibiting ions on aluminum has been studied using a radioactive labeling method. …

LANTHANUM-BASED MATERIALS FOR NUTRIENT PHOSPHORUS REMOVAL FROM AQUEOUS SOLUTION: OPTIMIZATION, CHARACTERIZATION AND APPLICATION
… most effective and efficient with the highest phosphate adsorption capacity. On the other hand, the incorporation of lanthanum into polymeric hydrogel bead and membrane allows the materials to be used in column filtration and membrane filtration, respectively. All synthesized lanthanum-based …

The effect of flyash on the removal of soluble phosphate from solution
… was to determine the feasibility of soluble phosphate removal in a flyash contact system. The investigation consisted of experiments involving batch adsorption studies and continuous flow studies. Removal kinetics and relationships between contact time, “t” , and flyash concentration, …

Nuclear magnetic resonance investigation of mineral surface reactions involving inner-sphere and outer-sphere complexes
… nuclear magnetic resonance (NMR) spectroscopy. Phosphate and Cs are good examples of inner-sphere and outer-sphere complexes, respectively, and this study shows that NMR is in many ways a more useful tool to investigate surface adsorbed species than other spectroscopic methods. Chapter 1 reviews …

Solute dispersion in selected tropical soils
… of chloride, nitrate, potassium, calcium, and phosphate was investigated in three tropical soils represented by three Hawaiian soils through a specially designed flow apparatus. Observed differences in the dispersion of these solutes for the range of velocities tested were attributed to …

Development of adsorbent materials for phosphate recovery
Phosphate, one of the primary components in fertilizers, is a finite resource in current scarcity, mainly obtained by the mining of phosphate rocks. In 2014, this mineral was declared as one of the 34 critical resources in the European Union. Phosphate rocks are geographically concentrated but …

Mineral requirements of selected species of aquatic hyphomycetes
… element, the nutrient salts were purified by the phosphate adsorption and dithizone methods. In addition to nutrient salts and purified water, the media contained only glucose. Since all the species except Clavariopsis aquatica DeWildeman grew well for many transfers and approximately two years on …
