The comparative study of pH and electrical conductivity in aqueous suspensions of clinoptilolite tuffs

A chemical behaviour in aqueous solutions of natural zeolitic material originated from three different deposites, with different content of major mineralogical component-clinoptilolite was examined. Examinations were performed trough monitoring of pH and electrical conductivity suspensions of natural zeolite - doubly distilled water. The results obtained during monitoring observed a nonstoichiometry between species included in ion exchange process, as well as amphoteric character of zeolitic tuff in suspensions with different initial pH values and tendency of neutralisation from initial solutions.
