Abstract: The need for selective sorption of trace concentrations of toxic Se(IV) and As(V) oxyanions, especially in the presence of competing high concentrations of sulfate ions, is well recognized. In this regard, previous ...

Abstract: Sufficient experimental data are presented here to verify the chromate ion‐exchange mechanism proposed earlier by Sengupta and Clifford (1986a). Most of the experiments were tailored to prove the validity of the mechanism, ...

Abstract: This study examines the use of ion-exchange fibers (IX fibers) to permanently sequester carbon dioxide present in flue gas into an aqueous phase as calcium or magnesium alkalinity while concurrently softening hard water. ...
