| 摘 要： | 采用管式炉燃烧-红外吸收法对煤焦油中硫含量的测定进行了研究。在研究炉膛温度、延迟时间、比较水平和称样量等对硫含量测定影响的基础上，优化了工作参数。当炉膛温度为900 ℃，延迟时间为30 s，比较水平为1.0，称样量为0.100～0.200 g之间时，硫的测定范围在0.005%～4%（质量分数）之间，校准曲线的相关系数大于0.9，RSD小于3%。本实验方法与国标GB387-90空气流-管式炉燃烧-亚硫酸-氢氧化钠滴定法对比，测定结果基本一致。

| Abstract: | The determination method of Sulfur in Coal tar by LECO SC-432 Sulfur analyzer was reported in this paper. The combustion temperature,combustion time,sample weight and standard reagent was selected.Compared with the GB/T387-90,the results obtained showed that the Sulfur analyser can be used in determinate sulfur of coal tar. The method was proved to be accurate,convenient and rapid. |
