前言:煤及焦炭总硫分的测定方法,一般有重量法与燃烧法二种。重量法是标准方法,於公断分析、精确测定时适用;作普通分析时常压其手续繁复,花费时间,大批操作,实感困难。燃烧法是测定可燃硫而近似计为总硫分,虽快速,但由於试样中硫酸盐不能烧出,引起不可避免的误差。此种以硫酸盐形式存在的硫分,据记载常在0.1%左右,但也有较多的(本人在工作时曾遇到0.5%的)。在综合性试验室,由於样品来自四面八方。用燃烧法
Foreword: Determination of total sulfur and coal coke method, there are generally two kinds of weight method and combustion method. Gravimetric method is the standard method, in the analysis of the public outbreak, the precise determination of the time; for routine analysis of the frequent pressure of complicated procedures, spend time, a large number of operations, real sense of difficulty. Combustion method is the determination of flammable sulfur and approximately as total sulfur, although fast, but because the sample can not be burned out of sulfate, causing the inevitable error. Sulfur content of this sulfate form, according to the record is often about 0.1%, but there are more (I have encountered at work 0.5%). In a comprehensive laboratory, samples come from all directions. Burning method
