Solubility of Cd2+, Cu2+, Pb2+, and Zn2+ in aged coprecipitates with amorphous iron hydroxides

Article Abstract:

Laboratory simulations of cadmium, copper, lead and zinc solubility in the presence of iron hydroxides coprecipitates reveal that the final soluble concentrations after aging stand at 59%, 58%, 94% and 100% respectively. The study shows that lead and zinc solubility are altered little with changes in pH brought about by ageing and that copper solubility increased as pH decreases due to age.

Copper Phytotoxicity in a Contaminated Soil

Article Abstract:

This study examines the effects of metal-adsorptive materials on long-contaminated mineral soil. The study concludes that the metal-specific effects occurred in the reduction of soluble concentrations of reactive oxides.

Adsorption of bacteriophages on clay minerals

Article Abstract:

Research indicates that a determination of surface potentials and surface hydrophobicities is essential in order to develop a model that predicts the sorption of these microorganisms on soil systems.
