The results of research of the chemical
activation process of clinoptilolite from Sokirnytskyi
field are shown. As a result of the research, the
effectiveness of the influence on zeolite hydrochloric
and sulfuric acids are compared. It should be noted that
the advantage is on the side of hydrochloric acid. It was
established that the increase in the concentration of
sulfuric acid and the time of zeolite processing leads
only to the increase in the content of the amorphous
phase. As a result of the experiment, optimal conditions
for zeolite activation: reagent – hydrochloric acid,
concentration of acid – 7 %, the processing time – 2 hours, phase ratio T:R – 1:2 were selected.
