Studi Penyerapan Ion Pb2+ oleh Zeolit 4A yang Disintesis dari Abu Terbang

Abstract

Research of study adsorption of ion Pb²⁺ by zeolite 4A has been done. This study aims to determine maximum of pH and concentration of Pb²⁺ for adsorption by zeolite 4A. This study uses variation pH of 4,8; 5,0; 5,2; 5,4 and 5.6; and variation concentrations of 40, 45, 50, 55, 60 and 65 ppm. Concentration of the adsorbed Pb²⁺ was calculated from the difference between the initial Pb²⁺ before the adsorption with the residual concentration of Pb²⁺ (measured). Measurement of residual concentration of Pb²⁺ using Atomic Absorption Spectroscopy (AAS). The result showed the maximum pH is 5,4 by the adsorption capacity is 14.7511 mg/g zeolite, and maximum initial concentration of Pb²⁺ by the adsorption capacity is 15.6438 mg/g zeolite.
