Очищення промислових стоків від сульфідів адсорбційним методом

Abstract

It has been developed an alternative method of purification of aqueous sulfide alkaline solutions (wastewater) from sulfide and hydrosulfide ions by their adsorption on pre-regenerated sorbent mixture consisting of activated charcoal of brand Decolar A and kieselguhr of brands Becogur 200 and Becogur 3500 with mass ratio of 4 : 6. It has been found that the degree of purification of the investigated solutions, which is strongly dependent on the initial concentrations of sulfide and hydrosulfide ions, is 95.7–96.6 % and indicates the high efficiency and possibility of using such technologies in industrial production.
