高效液相色谱法测定饮用水中甲萘威

Determination of Carbaryl in Drinking Water by High-Performance Liquid Chromatography

参照卫生部2001年制定的《生活饮用水卫生规范》,采用高效液相色谱法对饮用水中的甲萘威进行了检测,并对检测方法进行了线性方程、精密度和准确度实验:其线性相关系数等于0.999 6,相对标准偏差为0.326%,不同浓度的样品加标回收率均高于92.0%。方法操作简便、准确可靠、灵敏度较高,适合于地表水及饮用水中甲萘威的检测。

This study adopted high -performance liquid chromatography to detect the carbaryl in drinking water, which was recommended in the Drinking Water Hygienic Standard made by the Ministry of Health in 2001. Meanwhile, we tested the method by regarding linear equation, precision and accuracy. And found its linear correlation coefficient was 0. 999 6, RSD was 0.326% and the recovery of different concentrations about carbaryl was more than 92.0%. This procedure showed good accuracy, reproducibility and sensitivity, and was suit for the detection of carbaryl in surface water and drinking water.
