A reaction between poly(4-vinylpyridinium) cation and poly(ethylenephosphate)anion in an aqueous solution in the presence and absence of NaCl, NaBr, KCl salts and aminoacetic acid (Glycine) which has zwitter ionic property was studied by conductometry. The ionic interaction of polycation and polyanion gave a Polyelectrolyte Complex Gel formation. The resultant polyelectrolyte complex (PEG) contained polyanion in excess to stoichiometric ratio in salt free and in salt solutions. The PEC sorbed mono and divalent salts from the electrolyte solutions of NaCl, KCl and CaCl2. A triple interaction between polycation, zwitter ion and polyanion was suggested from the experimental data.
