Investigation of interactions in the cenospheres-electrolyte system

Abstract

The chemical composition of cenospheres have been studied by the methods of physical and chemical analysis. The products of their interaction with water and solutions of hydrochloric acid, sodium hydroxide and sodium chloride have been determined. It has been established that cenospheres dissolve in aqueous solutions regardless of pH. Pre-treatment of cenospheres in water and solutions of hydrochloric acid and sodium hydroxide reduces their dissolution in sodium chloride solution. Calcium ions, bicarbonate ions, silanol and aluminol groups of the surface participate in the ion exchange.
