Abstract—The aim of this study was to develop a procedure for preparing biosorbent from natural material pectin and chitosan. The method to prepare biosorbent pectin-CMCBADGE is established by using Reflux method. Pectin– carboxymethyl chitosan crosslinked with BADGE (bisphenol A diglycidyl ether) where BADGE was used as the crosslinking agen and chitosan was grafted with acetate to form carboxymetyl chitosan (CMC). The result of this study was biosorbent Pectin-CMC-BADGE could increased sorption capacity for remove heavy metal ions in waste water by adsorb lead (II) ion. The structure and the morphology of the resulting adsorbent were characterized by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The mass adsorbent adsorb Pb (II) was 15 mg with 94.78% of adsorption and adsorption capacity was 30.29 mg/g. Optimum contact time to adsorb Pb (II) was 60 minutes with 99.13% of adsorption and adsorption capacity was 44.33 mg/g. Optimum pH to adsorb Pb (II) was at pH 5 with 97.73% of adsorption and adsorption capacity was 45.03 mg/g.

Index Terms—CMC, pectin, pectin-CMC-BADGE, adsorbent, Pb(II).
