摘要
A rapid detection method of pesticide residues in milk by enzyme inhibition was researched. Construction of a quickly reaction system of enzyme inhibition for determination of organophosphorus and carbamate pesticide residues was achieved. The analysis of color reactions of milk showed a good correlation between color intensity and content of tolclofos-methyl, methamidophos and isoprocarb 1-naphthalenyl methyl carbamate. The detection limits of the four pesticide were 0.5~1.0 mg/kg, which were below the level of detection required to satisfy legislation in china. This method is simple and inexpensive and suitable for rapid detection of pesticide residues in milk.
