An indirect hydrogen sulfide conversion process for the production of elemental hydrogen and sulfur. The process is based upon the electrochemical oxidation of iodide in an aqueous solution with a pH in the range of 0 to 1 at high current densities and current efficiencies. Hydrogen gas is produced concurrently with soluble triiodide. Treatment of a gaseous or non-aqueous liquid stream with electrolyte solutions containing triiodide yields a sulfur product in plastic form. The sulfur product can be recrystallized from a solvent to yield sulfur of comparable purity to that presently produced.
