水体中毒死蜱提取及测定的两种方法比较

Abstract

Abstract:

We compared two different extraction and determination approaches of chlorpyrifos in water. The approach of petroleum ether extraction and UV spectrophotometer determination is simpler and quicker, so it can be employed for initial screening of massive samples. The approach of ethyl acetate extraction and HPLC determination has higher precision than the former approach, but it is timeconsuming and laborious, so it is suitable for the accurate determination of a small quantity of samples. The minimum detectable concentrations of these two approaches are 0.1 mg·L^-1 and 0.02 mg·L^-1, respectively.

Key words: chlorpyrifos, extraction, determination
