摘要
本文采用燃烧方法将不同形式的可燃性硫转化为SO2,在硝酸介质中用H2O2将SO2氧化为SO2-4,并用离子色谱法测定。结果表明,该法样品处理简单,干扰离子少,灵敏度高,能较准确测定出丙烯中的微量硫。
A sensitive and selective method for the determination of trace sulphur has been developed. Different formals of combustible sulphur are tranfered to SO2 with the method of combustion. In the medium of HNO3, SO2 is oxidized to SO2-4 by H2O2, which is determined by ion chromatography. The proposed method is simple, selective and has been used for the determination of trace sulphur in propene with satisfactory results.
