Determination of Sulphur by Hydrogen Reduction—Polarographic Analysis
-
摘要: 在600~900℃的溫度范圍內,用氫氣還原-極譜分析法測定了堿土金屬硫化物MgS、CaS和BaS以及稀土硫化物RB2S3與稀土硫氧化物RE2O2S被H2還原時S的析出率,以尋求用H2還原法分離鋼鐵試樣中FeS與其它堿化物的條件。
在800℃時,各硫化物被H2還原程度按以下順序遞減: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. -
