摘要：本方法研究了液上空间气相色谱法测定工业废水１，１，１－三氯乙烷、四氯化碳、三氯甲烷三种挥发性卤代烃，采用填充气相色谱法以角鲨烷为固定液，用ＣｈｒｏｍｏｓｏｒｂＧＡＷ－ＤＭＣＳ作为担体，在选定的条件下，１，１，１－三氯乙烷、四氯化碳、三氯甲烷能完全分离．同时也能与经常共存的二氯甲烷、三氯乙烯、四氯乙烯、一氯二溴甲烷、三溴甲烷完全分离而互不干扰。本方法的定性检出限是按全程序空白值标准偏差的３倍值计算。１，１，１－三氯乙烷、四氯化碳、三氯甲烷的定性检出限分别为２．４×１０－２ｎｇ、２．１０×１０－４ｎｇ、０．１３ｎｇ，当进样量为２０ｕｌ时，１，１，１－三氯乙烷、四氯化碳、三氯甲烷的最低检出浓度分别为１．２×１０－３ｍｇ／１、１．０８×１０－５ｍｇ／１、６．４８×１０－３ｍｇ／ｌ。
Determination of 1,1,1-trichloroethane,carbin tetrachloride,chlotoform in industrial wastewater by headspace-gas chromatography was studied.Packed gas Chromatograhy was used with squalane as stationary liquid,Chromosorb GAW-DMCS as supporter.Under specific condition,1,1,1-trichloroethane,carbon tetrachloride, chloroform,dichloromethane,trichloroethylene,tetrachloroethylene,dibromocholromethan e and bromoform could be well separated and did not interfere with oneanothEr.Qualitative limit that was three times of relative standard deviation of blank value has been calculated.Quantitative limit of 1,1,1-trichloroethane,carbon tetrachloride and chloroform was respectively 2.4×10-2 ng,2.16 x10-4 ng and 0.13ng.When inputvolume of sample was 20ul,minimum detecting concentration was respectively 1.2×10-3 mg/L,1.08×10-5 mg/L.and 6.48×10-3mg/L.
