Abstract

The variation of the distribution ratio Rd as a function of aqueous volume to solid mass ratio (V/M) for several sorption systems involving the cations Zn2+, Co2+, Ba2+, the anion I− and different solid matrices has been extensively examined. Empirical relationships for the concentrations of the sorbed species in the aqueous and solid phases as well as for the distribution ratio Rd are proposed. Generally Rd is found to increase with increasing V/M for tracer concentrations. A gradual increase in the initial concentration of the sorbed species eventually leads to a decrease in Rd with V/M.
