通过使用四氯乙烯代替四氯化碳测定水中油类物质的对比实验，得到如下结论：四氯乙烯作萃取剂时，标准曲线线性相关系数为0．9999，检出限为0．336mg／L，精密度和准确度符合质控要求。但标准曲线方程的斜率较差，在分析浓度较低的样品时，准确度相对误差较大，萃取回收率不高。由此可以看出，使用四氯乙烯分析油类物质的局限性较大，分析方法还需进一步研究。

By conducting contrast experiments for determination of oil in water using tetrachloroethylene instead of carbon tetrackloride, it concluded that when tetraehloroethylene was used as extractant, the liner correlation coefficient was 0. 9999, detection limit was 0. 336mg/L and the precision and accuracy met the requirements of the quality control. However the slope of the standard curve equation was low. When samples with low concentration were analyzed, the relative errors of accuracy were low and the extraction recovery was poor. It concluded that there were still limitations to use tetrachloreethylene for determination of oil in water, so the method needs further studies.
