Abstract

The Li-, Na-, K-, Cs-, Ca-, Ba-, and NH4-forms of natural clinoptilolite from the White Stratum deposit, Bulgaria, have been obtained by ionic exchange in solutions. The1H NMR spectr of the samples have been recorded at room temperature and the dipole-dipole coupling constants of zeolite water protons have been measured. The characteristics of regular redistribution of water molecules in structural positions of clinoptilolite upon substitution of exchange Na and Ca cations by the larger K and Ba cations have been established.
