    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.

    Reactions of sulfenyl chlorides of substituted 1,4-naphthoquinone
    (Publishing House of Lviv Polytechnic National University, 2011) Musyanovych, Rostyslav
    Conditions of sulfenyl chlorides of substituted 1,4-naphthoquinone reactions with unsaturated compounds with the formation of new sulfides, thiones and 2-thiabicyclo[2.2.1]heptene and thiopyrane substances have been investigated. Досліджено умови перебігу реакцій сульфенілхлоридів заміщеного 1,4-нафтохінону з ненасиченими сполуками з утворенням нових сульфідів, тіокетонів та 2-тіабіцикло[2.2.1]гептенових та тіопіранових сполук.
