2021 JKM audy COMPUTATIONAL STUDY OF ZEOLITE LTA ( LINDE TYPE A) INTERACTION WITH ALKALINE CATION (Li+, Na+, K+) USING MOLECULAR MECHANIC METHOD
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/Al 2,4286 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.
