Abstract. 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.

Key words: zeolite, acid activation, clinoptilolite, adsorbent.
