gb 7492-1987 水质 六六六、滴滴涕的测定 气相色谱法

本标准适用于地面水、地下水以及部分污水中六六六、滴滴涕的分析。 本方法用石油醚萃取水中六六六、滴滴涕,净化后用带电子捕获检测器气相色谱仪测定。当所用仪器不同时,方法的检出范围不同。γ-六六六通常检测4ng/L,滴滴涕可检测200ng/L。 样品中的有机磷农药、不饱和烃以及邻苯二甲酸酯等有机化合物在电子捕获鉴定器上也有响应,这些干扰物质可用浓硫酸除掉。

GB 7492-1987 Water quality - Determination of hexachlorocyclohexane and DDT - Gas chromatography method





This standard is applicable to the analysis of BHC and DDT in surface water, groundwater, and some wastewater. In this method, BHC and DDT in water are extracted with petroleum ether, purified and determined by gas chromatography with electron capture detector. When different instruments are used, the detection range of the method varies. γ- BHC is usually detected at 4ng/L, while DDT can be detected at 200ng/L. Organophosphorus pesticides, unsaturated hydrocarbon, phthalates and other organic compounds in the sample also respond on the electron capture analyzer, and these interfering substances can be removed with concentrated sulfuric acid.
