半连续高浓缩比液液萃取气相色谱法分析饮用水中的六六六、滴滴涕

Determination of BHC and DDT in Drinking Water by Half-sequence and High Ratio Liquid-liquid Extraction Gas Chromatographic Method

本文针对我国目前实施的饮用水水质监测标准中两项非挥发性有机物六六六、滴滴涕,利用实验室自制简单的高浓缩比液液萃取装置,报道了一种简单快速测定水中六六六、滴滴涕的气相色谱法。方法的最低检测限低于1ng/L。

Hexachloro-cyclohexane (BHC) and Dichlorodiphenyl trichloroethane (DDT) are two non volatile organic substances listed in the current Chinese National Standards for drinking Water Quality. A simple half-sequence and high ratio liquid-liquid extraction LLE gas chromatographic method can be obtained in this article. The detection limits of the two targets substance are all below 1ng/L.
