Removal of heavy metals from aqueous solutions using microgas dispersions.
Abstract
Flotation by means of microgas dispersions was used to remove copper, chromium, nickel, lead, and zinc from aqueous solutions after precipitation including an industrial plating effluent. Metal removals of up to 100% were obtained from solutions of the metals ranging in concentration from 2 to 20 ppm. (A)
