The functional shape of a sorption isotherm is determined by underlying molecular interactions. However, doubts have been raised on whether the mechanism can be understood in principle from analyzing curves via range competing models. We shown recently that it possible to translate interactions rigorous statistical thermodynamics. aim this paper fill gap between thermodynamic theory and experim...

Zeolites due to their structures can be used as molecular sieves for purification of materials and solutions. Zeolites with PHI and SOD structure are so common and applicable for this purpose. Hydroxy sodalite and phillipsite are the more abundant members of zeolites which display good selectivity for very small molecules and some ions such as Sr, Pb, Zn, Cu and Rb. There is not any pure natura...
