The result shows that the structure of zeolite RHO with Si/Al ratio 3.36 has the most stable structure with a 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. %U http://jurnal.kimia.fmipa.unmul.ac.id/index.php/JKM/article/view/217 %J JURNAL KIMIA MULAWARMAN %0 Journal Article %V 14 %N 1 %@ 2476-9258 %8 2016-11-08
