ABSTRACT:
A process for converting sulfide ion present in a solution to innocuous, water soluble sulfur species is provided. The process basically includes the steps of contacting the sulfide ion with an oxidizing agent to oxidize it to the water soluble sulfur species and admixing a surface active agent with the solution in an amount sufficient to inhibit precipitation of elemental sulfur and to promote subsequent oxidation. To enhance the formation of the water soluble sulfur species and to speed up the reaction, the oxidation reaction is conducted under alkaline conditions.
