摘要
采用气相色谱-硫化学发光检测器(GC-SCD),对炼厂C_4中的硫化物进行定性和定量研究,定性根据色谱柱的性质、硫化物保留时间及沸点规律,在此基础上考察了SCD检测器对不同硫化物的响应关系。实验结果表明,SCD检测器与硫化物呈等摩尔响应,与硫化物形态无关,该方法相对标准偏差RSD<5%,回收率达到95.5%～106%。
Gas chromatography- sulfur chemiluminescence （GC-SCD）was used for the qualitative and quantitative analysis of sulfur compounds in the refinery C4,the qualitative analysis depend on chromatographic column, chromatographic retention, boiling point of the sulfides; and the work curves of the sulfides was researched with better linear ranger, the relative standard deviation for the method was RSD 〈 5% with 95.5%-106% recovery.
