Abstract : The aims of this study was to determine the effect of pH on adsorption of Hg(II), Pb(II) and Ca(II) simultaneously. The dithizon-immobilized zeolite adsorption has been successfully synthesized for adsorption of Hg(II), Pb(II), and Ca(II) simultaneously. The dithizon-immobilized zeolit was synthesized by immobilize dithizon on the natural zeolite surface that has been activated with HCl. The results of immobilization are then characterized using FTIR and XRD. Adsorption of Hg(II), Pb(II) and Ca(II) was studied by determining the optimum pH of zeolite without dithizon-immobilized adsorbent (ZAA-T) and dithizon-immobilized zeolite (ZAA-D). The results showed that adsorption of Hg (II) and Pb(II) on zeolite without dithizon-immobilized adsorbent and dithizon-immobilized zeolit optimum at pH 5, while adsorption of Ca (II) was optimized at pH 6 in zeolite without dithizon-immobilized adsorbent and in dithizon-immobilized zeolite optimum at pH 7. Keywords: Adsorption, Mercury, Lead, Calcium, Zeolite, Dithizon.
