| 摘 要： | 空气中三氯苯胺用５０％乙醇吸收，经ＯＶ－１７和ＯＶ－２１０混合色谱柱分离，电子捕获检测器检测测定。对采样及测定条件，用正交试验进行了优选。方法的检出限为０．０１ｍｇ／Ｌ，当标准溶液浓度为０．５～１０ｍｇ／Ｌ时，相对标准偏差为４．３％～３．７％。线性范围为０．０２～４０ｍｇ／Ｌ。采样效率为９９．１％～１００％。样品在采样管中可稳定１５天以上。通过现场试验和验证试验，证明该方法准确可靠、快速简便，完全适用于空气中三氯苯胺的测定。各项试验指标符合劳动卫生监测要求。

| Abstract: | Trichloroaniline in the air was collected with 50% ethanol and separated with a column OV-17:OV-210 ECD as a detector. The best conditions of sampling and determining were selected through the orthogonal experimental design. The detectable limit was 0.01 mg/L. When the concentration of trichloroaniline in the air was 0.5-10 mg/L, the relative standard deviation (RSD) was 4.3%-3.7%. There was a linear relation within the range of 0.02-40 mg/L. The sampling efficiency was 99.1%-100%. The samples were stable for at least 15 days. It is proved that this method is accurate, fast, simple and sensitive. It is suitable for the determination of trichloroaniline in the air. |
