Preparation of Pb(II)-Carboxymethyl Chitosan Pec PEGDE Film as Selective Asorbent for Removal Pb(II) Ion

Abstract

The aims of this research is to synthesize Pb(II)-Carboxymethyl Chitosan-Pectin crosslinked Polyethylene Glycol Diglisidyl Ether (Pb(II)-CCPecP) film by using templated ion of Pb 2+ as selective adsorbent for Pb(II) ion. The structure of Pb(II)-CCPecP film adsorbent were characterized by FT-IR and scanning electron microscopy (SEM). The adsorption properties of Pb(II)-CCPecP film adsorbent in order to adsorp of Pb(II) ion in presence Cu(II) and Zn(II) were evaluated. FT-IR showed visible peak at 3441 and 1628 cm -1 indicate the film adsorbent have -COOH and -OH active group. The SEM of Pb(II)-CCPecP film show smoother surface and some holes and gaps are formed. The optimum condition for adsorption of Pb(II) ions by Pb(II)-CCPecP film adsorbent was occur at pH 5 and 200 min contacting time. The adsorption of Pb(II)-CCPecP film adsorbent toward Pb 2+ was higher compared with Zn 2+ and Cu 2+ metal ion. The results revealed that the film was capable to removal of Pb(II) ion selectively in solution containing single metal ion or coexistence of three metals ion of Zn 2+ and Cu 2+ .

Kinetic and thermodynamic biosorption of Pb(II) by using a carboxymethyl chitosan–pectin–BADGE–Pb(II)-imprinted ion polymer adsorbent

“…The morphology of Pec by SEM analysis shows a coarse structure distributed into the particles. The morphology of CS and CC is much smoother than that of the Pec surface, which is flake forming, fibrous and non-porous [11]. The surface morphology of SEM of Pec, CS and CC is shown in figure 1.…”
