    Adsorptive desulfurization of industrial wastewatern
    (Видавництво Львівської політехніки, 2020-02-10) Khudoyarova, Olga; Gordienko, Olga; Sydoruk, Tetiana; Titov, Taras; Petruk, Roman; Prokopchuk, Serhii; Vinnytsia Mykhailo Kotsiubynskyi State Pedagogical University; Vinnytsia National Technical University
    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.

    Electrochemical extraction of zinc from acid and neutral regeneration solutions
    (Lviv Politechnic Publishing House, 2018-10-26) Koliehova, Anastasiia; Trokhymenko, Hanna; Gomelya, Mykola; Admiral Makarov National University of Shipbuilding; National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”
    The results of the electrochemical separation of sulfate and zinc chloride regeneration solutions; the pH influence on the electrolysis process and the extracting efficiency of metallic zinc are presented in the work. It has been established that electrolysis should be carried out in a two-cell electrolyzer to remove metals effectively.
