Determination of Sulphur by Hydrogen Reduction—Polarographic Analysis

    Graphical Abstract
    • Abstract
  • Experiments on the extraction of sulphur from the sulphides and oxysulphides such as MgS, CaS, BaS, RE2S3 and RE2O2S by hydrogen reduction have been carried out at 600~900℃ by means of hydrogen reduction-polarogra-phic analysis method. The reduction degree of various sulphides by H2 at 800℃ is in the order of decreasing as follows:FeS>MgS ≥ RE2S3>RE2O2S ≥ CaS=BaS.
