水体氨基甲酸酯类农药总量快速检测方法

Rapid Detection Method of Total Amount of Carbamate Pesticides in Water

摘要:

设计、开发了氨基甲酸酯类农药（CMs）长效检测剂，借助混匀仪、消解仪对水中CMs进行提取、碱解，再利用长效检测剂、便携式水质检测仪实现CMs的现场快速检测。该方法相对标准偏差（RSD）为2.86%（0.8 μmol·L^-1 CMs）和1.61%（2.4 μmol·L^-1 CMs），检出限（LOD）为0.07 μmol·L^-1，检测周期仅40 min，实际水样加标回收率为60%~78%，太浦河水样加标分析结果表明该快检法和GC-MS检测结果具有较好的一致性。

Abstract:

A long-acting detection agent for carbamate pesticides （CMs） was designed and developed. The CMs in water were extracted and alkalized by mixter and digester， and then the long-acting detection agent and portable water quality detector were used to realize the rapid detection of CMs on site. The relative standard deviations （RSDs） of this method are 2.86% （0.8 μmol·L^-1 CMs） and 1.61% （2.4 μmol·L^-1 CMs）， the limit of detection （LOD） is 0.07 μmol·L^-1， the detection period is only 40 min， and the spiked recovery of real water samples is 60%~78%. The analysis results of the spiked water samples from the Taipu River show that the detection results of rapid detection method and GC-MS have good consistency.
