焦炭中全硫含量的测定

Determination of total sulfur content in coke

采用库仑滴定法和红外吸收法来测定焦炭中的全硫含量,比较两种方法的准确度和误差范围。结果显示两种测试方法所得结果基本一致,没有明显差异,但从相对标准偏差来看,红外分析测试方法的准确度略高。

The total sulfur content in coke was determined by coulometric titration and infrared absorption,and the accuracy and error range of the two methods were compared.The results show that the results obtained by the two methods are basically the same.And there is no significant difference between them.However,from the relative standard deviation,the accuracy of the infrared analysis test method is slightly higher.
