副产氯化氢中三氯乙烯含量测定
|
摘要
通过气体量管采样吸收后萃取,研究了采用气相色谱法测定副产氯化氢中三氯乙烯含量的方法。结果表明,在实验条件下,方法检出限为体积分数0.006%,检测范围为体积分数0.006%～1.5%,相对标准偏差小于5%,适用于三氯乙烯生产过程副产氯化氢气体中三氯乙烯含量分析。
The determination of trichloroethylene content in by-product hydrogen chloride by gas chromatography was studied by gas flow-tube sampling,absorption and extraction. The results showed that under the experimental conditions,the detection limit of the method was 0.006% volume fraction;the detection range was 0.006% to 1.5% volume fraction;the relative standard deviation was less than 5%;which was suitable for trichloroethylene content analysis in by-product hydrogen chloride during trichloroethylene production process.
