Abstract:
A new alka linehydro lysis m ethod is developed fo r rap id ly detecting organophospha te pesticide residues in vege tab les. Its princ ip le is based on the fact that org anophospha te pestic ide hydro ly zes and its hydro lysate is ox id ized by purpurea l ox idizing so lu tion. The de tecting resu lts show that the detecting sens itiv ity ranges from 0. 5~ 5 mg /kg, the tim e of detection is 5~ 10m in and the cost of detection is about 0. 012 US do llar . And it is a s imp le, conven ient and quick me thod o f de tecting organopho sphate pestic ide residues, and can be used to check fo r leve ls o f pestic ide residues in fam ily or ma rket w ithout o ther instrument
