Abstract
The kinetics of cadmium release and copper uptake in a cadmium sulfide suspension was monitored under several environmental conditions. A la ttice exchange reaction between dissolved copper and cadmium sulfide s toichiometrically produces CuS(s) and releases divalent cadmium into s olution. This reaction is slightly enhanced by photo-irradiation, howe ver, is not affected by dissolved oxygen. Under low concentrations of Cu(II), both lattice exchange and photo-oxidative dissolution of CdS(s ) take place.
