KAJIAN PERUBAHAN UKURAN RONGGA ZEOLIT RHO BERDASARKAN VARIASI RASIO Si/Al DAN VARIASI KATION ALKALI MENGGUNAKAN METODE MEKANIKA MOLEKULER
ABSTRACT: The structure
modeling of zeolite RHO with variation of Si/Al ratio (5; 4.33; 3.8; 3.36; 3;
2.69; 2.43; 2.2; 2) and variation of alkaline cations (Li+, Na+, K+, Rb+, Cs+,
Fr+) calculated by the molecular mechanics method has been investigated. The
result shows that the structure of zeolite RHO with Si/Al ratio 3.36 has the
most stable structure witha minimum energy 2652.0308 kcal/mol. The most stable
structures of zeolite RHO impregnated with cation is that impregnated with Fr+
(alkaline) with a minimum energy 3006.6587 kcal/mol. The result shows that the
zeolite RHO structure with cations Fr+ (alkaline) has the largest pore diameter
which potentially has the best adsorption capacity.
