“…After being cross-linked with pectin, three peaks appeared at 1554 cm −1 , 1630 cm −1 , and 1750 cm −1 (Figure 1). The peak at 1750 cm −1 is characteristic of C=O vibration of the COOH group in pectin (Kim et al, 2003;Bernabé et al, 2005). Peak 1630 cm −1 is assigned to amide I and asymmetric NH 3 + deformation.…”

“…It is readily available, biocompatible, and bioresorbable. Pectin is a natural cross-linker and has been used to cross-link chitosan beads and membranes to modify their physical and chemical properties as well as biocompatibility (Kim et al, 2003;Bernabé et al, 2005;Ghaffari et al, 2007). Pectin, an anionic polysaccharide, will form polyelectrolyte complex with chitosan, a cationic polysaccharide, through ionic attraction between NH 3 + of chitosan and COO − of pectin (Meshali & Gabr, 1992;Kim et al, 2003;Bernabé et al, 2005).…”

“…Absorption at 1627.92 cm -1 is a specific absorption for -COOH group [14]- [16]. CMC-Pec-BADGE characterization by using FTIR shows that this material has an active force hydroxide (-OH) indicated by the spectra with wave numbers 3425.58 cm -1 and the active carboxylic group (-COOH) at wave number 1604.77 cm -1 and bands related to C=O stretching of the ester could be observed at 1743,65 cm -1 [17]- [19]. Peak on 833.25 show peak of C-H substituted para on the benzene ring, it indicate BADGE have been crosslink into pectin and Chitosan.…”

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-CMC-BADGE is established by using Reflux method. Pectincarboxymethyl 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.

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.
