In determining aluminum and sulfur in ferro-molybdenum, iron and molybdenum were removed by using methyl-isobutyl ketone extraction method. After the removal of iron and molybdenum, aluminum was determined gravimetrically or volumetrically by using oxine, by which 0.1∼1 per cent aluminum in ferro-molybdenum was determined. By using methyl-iso-butyl keton for ether, the danger of explosion caused by organic vapour and the disturbance of molybdenum were avoided. Sulfur was determined gravimetrically as barium sulfate down to 0.005 per cent content of it. The present procedure is superior in its simplicity and in being free of the obstruction by molybdenum trioxide to the usual combustion method for sulfur.
