The influence of cavitation on the phase-disperse state of hydrated calcium oxide

The effect of cavitation phenomena excited by ultrasonic radiation and in a jet-type hydrodynamic cavitator on the change in the phase-dispersed state of hydrated calcium oxide was investigated. The influence of the conditions of cavitation activation of calcium hydroxide on the sedimentation stability of its suspension was established. Based on the analysis of the intensity of sedimentation of Ca(OH)2 particles after cavitation treatment of calcium hydroxide suspension, the probable course of this process in different time periods is proposed.

Ecological Sorbent Based on Saponite Mineral from Ukrainian Clay-Field

The physico-chemical, structural and adsorption characteristics of saponite mineral from Tashkivske clay-field and their changes under the influence of acid, thermal and ultrasonic activation were investigated. Stabilization mechanism of the colloidal system “saponite-water” under the influence of stabilizing agents was studied. Moreover, the effectiveness of saponite multipurpose usage was proved by experiments.
