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 Pb²⁺ 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 Pb²⁺ was higher compared with Zn²⁺ and Cu²⁺ 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 Zn²⁺ and Cu²⁺.
