Determination of Sulphur by Hydrogen Reduction—Polarographic Analysis
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.
