| Abstract: | The conditions for formation of complexes of copper(I) with mercapto compounds in aqueous- alkaline solutions and the catalytic activity of these complexes in oxidation of mercaptans and hydrogen sulfide was studied. The kinetic characteristics of these catalysts were compared with those of catalysts based on cobalt phthalocyanines. A method was proposed for suppressing formation of the thiosulfate ion in oxidation of H2S to elemental sulfur. |
