Abstract: The gases evolved from an aluminium laboratory cell were investigated. Carbon anodes contained different amounts of sulphur were used. The presence of COS and SO2 emissions was confirmed by analysis of the gasses, the major sulphurous compound was SO2. The content of sulphur in the electrolyte was measured by classical iodometry. The formation of metal sulphide was confirmed by XRD analysis of solidified cathode.
Keywords: aluminium electrolysis, anode gases, COS and SO2 emissions
