Preparation of Pb(II)-Imprinted-Carboxymethyl Chitosan-Pectin-BADGE Film as Sorbent for Pb(II) Ion
Abstract:
Cross-linked metal-imprinted Carboxymethyl Chitosan-Pectin (CMC-Pec) were prepared from CMC and pectin, using Pb (II) ion as a template and Bisphenol A diglycidil ether (BADGE) as the cross-linking agent. The film was prepared in order to obtain a selective adsorbent for Pb (II) ion. The film was characterized using infrared (IR) spectroscopy. The result showed that the active group of the Pb (II)-imprinted CMC-Pec-BADGE film was hydroxyl group (-OH) and carboxylic (-COOH) as indicated by IR peaks at the wave number 3300-3600 cm-1 and 1600-1800 cm- 1, respectively. The Pb (II) adsorption capacity of the Pb (II)-imprinted CMC-Pec-BADGE film was 12.18 mg/g. The film showed a selective adsorption for Pb (II) metal ions compared to the adsorption of Zn (II) and Cu (II) in mole ratio of 1: 1: 1.
