Abstract

Experimental
researches are conducted on samples of the two characteristic regions deposits
of bentonite-Kamenica and Vitia. Potentiometric titration method is used to
determine the ion exchange capacity of natural bentonite and activated with
acid. Within the paper is researched the impact of the degree of acid
activation in ion exchanger capacity of Kabashi bentonite. They used three
different concentrations of acid solution: 10 % HCl, 20 % HCl and 30 % HCl. The
natural bentonite of Karaçeva has shown greater capacity of ion exchange than
natural bentonite of Gushicë and Kabash. The ion exchange capacity of Kabashi
bentonite increase after acid activation compared with ion exhange of natural
bentonite.

Keywords
