MATHEMATICAL-MODEL FOR SORPTION CONCENTRATION PROCESS

On the basis on previous studies of the selective adsorption of platin um group metals by PAN--MVP fibers, the concentration process has been described for the cases of single-stage and multistage static sorptio n. General equations involving sorption equilibrium parameters, capaci ty characteristics of the sorbents, and various concentration variable s, have been derived for predicting sorption concentrating. The adequa cy of these equations has been confirmed by experiments on the adsorpt ion of hexachloroplatinate(IV) ions from chloride solutions.
