The Influence of the Polymeric
Matrix on the Development and Ageing of Ni(II)- and Co(II)-Containing Catalysts
upon the Liquid-Phase Oxidation of Sulfide-Anion by Oxygen
Abstract
The oxidation of S2--ion
by molecular oxygen over Ni(II)- and Co(II)-containing catalysts has been
investigated. It was shown that effects of the development and ageing of
catalysts during reaction connected with the metal ion nature and with the
presence or absence of polyacrylamide hydrogel as support. Duration of the
period of the catalyst development depends on conditions of formation of a
sulphide phase and doesn’t connect with catalitic properties of nickel and
cobalt sulphides. The changing of gel cross-linkage from 1 to 10% doesn’t
affect the activity and stability of catalysts.
