【摘要】 采用气相色谱法，以聚乙二醇为固定液，戊烷作萃取溶剂，进行了用氢焰检测器（ＦＩＤ）测定水中微量氯仿的实验研究．该法预处理回收率在９５％以上，线性范围为０～４４６μｇ／Ｌ，最低检出浓度５０．０μｇ／Ｌ．在无电子捕获检测器（ＥＣＤ）时，可用于水中微量氯仿的测定．更多还原

【Abstract】 A new gas chromatographic method for determining trace chloroform in water is established. The analytical procedures are as follows: estraction with pentane, separation with polythyleneglycol column chromatography and determination by FID. The extraction yield is above 95%. Linear range of the method is 0 446 μg/L with a detection limit of 50.0 μg/L. This method can be applied to determine chloroform in water with Gas Chromatography in the absence of ECD.更多还原
