Abstract
An alternative method of purification of
aqueous sulfide-alkaline effluents from sulfide and
hydrosulfide ions by their adsorption with mixed
sorbents based on activated charcoal and kieselguhr
has been investigated. High adsorption efficiency of
mixed sorbents for purification of model sulfide- and
hydrosulfide-containing solutions has been established.
The dependence of the extraction degree of sulfide and
hydrosulfide ions from aqueous solutions on their
concentration, adsorption time and sorbent mass used
has been investigated. The surface of mixed sorbents
after purification of sulfide-alkaline model solutions was
investigated by X-ray analysis, and the presence of
various modifications of sodium sulfide on the surface
was shown. The scheme of adsorption treatment of
industrial sewage with the use of mixed sorbents has been offered.
