Synthesis of Environmental Friendly Chelating Ion Exchange Resin Specific for Zinc

MAMTA AHUJA and P. N. MATHUR

An environmental friendly hydrophilic chelating resin based on naturally occurring polysaccharide, chitosan has been synthesized, characterized and the molar distribution coefficient values of different metal ions viz., Co(II), Ni(II) Cu(II), Zn(II), Ca(II), U(VI) and W(VI) on this resin were determined as a function of pH in the range 3-10. The quantitative separation of zinc-cadmium mixture was achieved on the resin at pH 9.
