摘要
采用吹扫捕集样品浓缩仪-气相色谱法,毛细柱分离分析聚氯乙烯工业废水和生活饮用水中的氯乙烯,实现氯乙烯及其干扰物质(乙炔、乙醛)的分离,方法检出限0.1μg/L,0~0.200mg/L浓度范围内线性良好,相关系数R^2≥0.999;对0.008mg/L,0.040mg/L的标准样品进行分析,相对误差为-11.5~7.5%,相对标准偏差为6.2~7.8%;分析生活饮用水和聚氯乙烯工业废水实际样品,相对偏差为0%~2%,加标回收率90%~92%。实验证明,该方法可有效地用于聚氯乙烯生产企业排放的工业废水和生活饮用水中氯乙烯的测定。
The detection limit was 0.1ug/L.The linear was good in the range of 0-0.200mg/L（R^2≥0.999）.The relative error was-11.5%-7.5%,The relative standard deviation was 6.2%-7.8%.The samples of PVC industrial wastewaster and drinking water were analyzed,the relative deviation was 0%-2%,the recovery of standards added to samples were 90%-92%.The experiment results show that the method can be used to determine vinyl chloride in the PVC industrial wastewater and the drinking water.
