摘要：
A modified pectin has been synthesized by reacting/combining -OH group among pectin and chitosan with ECH (Epichlorohydrin) croslinker agent. Chitosan was grafted with acetate to form carboxymetyl chitosan (CMC). The result of this study was Pectin-CMC-ECH film could be greater adsorp Pb(II) ion than chitosan without modified. The structure of Pectin-CMC-ECH film was characterized by Fourier transform infrared (FTIR) spectroscopy. Adsorption experiment were performed in batch processes; Result of the study showed that optimum conditions for the adsorption of Pb(II) on the adsorbent were found at pH 5 with with 93 % of adsorption and adsorption capacity was 42.77 mg/g, contact time 12 hour with 91 % of adsorption and adsorption capacity was 39.74 mg/g. Pectin-CMC-ECH film demonstrate the ability to absorb Pb (II) metal ions was higher than chitosan without modified.
