COMPUTATIONAL STUDY OF ZEOLITE LTA (LINDE TYPE A)INTERACTION WITH ALKALINE CATION (Li + , Na + , K + ) USING MOLECULAR MECHANICMETHOD
Abstract
Study of computation on zeolite LTA(Linde Type A) interaction with alkaline cation (Li+, Na+, K+) using mechanical moleculer method was conducted. Data processing was conducted computationally using Hyperchem 7.0 with the mechanical molecular method. The result of the study showed zeolite LTA with ratio Si/Al2,has the lowest minimum energy. Furthermore, impregnation by cation Li+ increases structure stability, and impregnation by cation Na+ has the largest diameter window on Zeolite LTA.
