Abstract

Sarulla natural zeolite was prepared as an adsorbent to remove heavy metals of Pb (II) and Cd (II) by batch method. Zeolite was activated with 200mL HCl 1.0N and after modification was conducted, the surface was clearer as well as the morphology, the particles were smoothly, therefore the surface area and the adsorption capability were increased. Based on mass variation of adsorbent obtained for both metals, the optimum conditions is 0.4gr, which absorption efficiencies of Pb (II) and Cd (II) were up to 40.51 % and 52.22 %, respectively. Then, Pb and Cd were adsorbed with pH maximum at 4, respectively as 41.78 % and 50.75 %. When beginning the absorption process of Pb ions, it could be immediately be absorbed with a significant amount and continued until the optimum conditions after adsorbed at 50 minutes with adsorption capability of 44.64 %. Cd metal also was absorbed slowly up to 30 minutes and absorbed with a significant amount after 50 minutes contacted time, which the absorption capability is higher than Pb as 56.92 %. The absorption capability of Cd metal was exceeded the Pb metal by using the Sarulla natural zeolite.
