Abstract
PRELIMINARY COMPARATIVE STUDY ON THE ADSORPTION OF MINOR ELEMENTS IN SODIUM SILICATE SOLUTION. Research studies on the adsorption capacity of Karangnunggal natural zeolite and activated carbon as a sorbent in solution of sodium silicate has been done. This study aims to determine the efficiency of adsorption of the zeolite and activated carbon to a solution of sodium silicate impurity elements such as Ca, Mg, Fe and Al and to know the relationship between the adsorption of the zeolite and activated carbon with the adsorption parameters. Determination of optimum conditions include the mass of adsorbent, pH, contact time and temperature of solution. Results of analysis using atomic absorption spectroscopy (AAS) showed that Karangnunggal natural zeolite is not effective to adsorb Mg and Ca ions in sodium silicate solution, but zeolite can adsorb Fe ion. The optimum condition of Fe ion absorption is achieved with contact time parameters for 60 minutes, the mass of zeolite is used as much as 3 gram, pH 3, and at room temperature. The highest adsorption efficiency by activated carbon on sodium silicate solution reached 88.4 3% for the Al ion and 41.6 % for Fe ion.
