    摘要: A process for removal of H.sub.2 S from gaseous streams is described, the process being characterized by division of the gaseous stream into major and minor portions, oxidation of the H.sub.2 S in the major portion with an oxidizing reactant solution comprising a polyvalent metal chelate or chelates of nitrilotriacetic acid, and utilization of the minor portion as a source of hydrogen ions to assist precipitation of ferrous oxalate from a bleed stream of the oxidizing reactant solution.
