Abstract
A process is disclosed for reducing the level of sulfides in aqueous solutiuons which comprises contacting a sulfide-containing solution having a pH value in the range from about 8.5 to 12 with oxygen in the presence of a flocculent manganese-containing catalyst having been prepared by aerating an aqueous solution of a divalent manganese salt, said salt solution having a pH value in the range from about 8.5 to about 12.
