氢还原—极谱法定硫

Determination of Sulphur by Hydrogen Reduction—Polarographic Analysis

    摘要
  • 摘要: 在600~900℃的温度范围内,用氢气还原-极谱分析法测定了碱土金属硫化物MgS、CaS和BaS以及稀土硫化物RB2S3与稀土硫氧化物RE2O2S被H2还原时S的析出率,以寻求用H2还原法分离钢铁试样中FeS与其它碱化物的条件。
    在800℃时,各硫化物被H2还原程度按以下顺序递减:FeS>MgS ≥ RE2S3>RE2O2S ≥ CaS≈BaS。

     

    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.
