Abstract—The aim of this study was to develop a procedure for preparing film polyelectrolyte complex pectine/chitosan with increased sorption capacity for heavy metal ions which could be used as adsorbent to remove lead (II) ion in waste water. A film of the polyelectrolyte complex between chitosan and pectin were prepared by mixing the complex of both polysaccharides. Firstly, chitosan was grafted with acetate to form carboxymetyl chitosan (CMC). Subsequently, CMC is mixed with pectin to form CMC/pectin film. The result showed that the optimum mass ratio of CMC:pectin to synthesis CMC-Pectin film was 70:30%, optimum adsorbent mass to adsorb Pb (II) was 10 mg with 70% of adsorption and adsorption capacity was 30.1 mg/g. Optimum contact time to adsorb Pb (II) was 75 minutes with 87% of adsorption and adsorption capacity was 40.0 mg/g. Optimum pH to adsorb Pb (II) was at pH 5 with 93% of adsorption and adsorption capacity was 42.7 mg/g.
Index Terms—CMC, pectin, CMC-pectin film, adsorbent, lead (II) metal ion.
