ADSORPTION OF CHROMIUM(VI) AND COPPER(II) IONS FROM WELL WATER IN CHALLAWA INDUSTRIAL AREA USING PECTIN-CHITOSAN POLYELECTROLYTE COMPLEX
ABSTRACT The aim of the research was to carryout adsorption study of the removal of chromium(vi) and copper(ii) ions from well water using pectin-chitosan polyelectrolyte complex as adsorbent. The optimum pH and ratio of pectin/chitosan was determined and the chitosan/pectin complex was characterized by using FTIR, BET, XRD, and SEM. Finally, removal efficiency of the PEC for chromium and copper was studied under optimum conditions. I.e. 0.4 g adsorbent mass, ...
