摘要
依据国标GB/T 214—2007《煤中全硫的测定方法》,利用标准煤样做对照,对测试高硫煤及低硫煤的测试方法进行了合理的改进。改进后测定煤中全硫的方法可缩短电解时间,而且其测定的准确度不受影响。
According to GB/T 214—2007 ＂the determination method of sulphur in coal＂,this paper introduced reasonable improvement method to determining the high sulfur content coal and low sulfur content coal compared to the standard coal.The improved method to testing the sulphur in coal can shorten electrolysis time and will not influence the accuracy.
