| Abstract: | Objective] The aim was to establish a microwave pretreatment method which could effectively remove organic sulfur in pesticide residue analysis.Method] Spicy flavor vegetables such as garlic and onions were treated by microwave,the removal effects of microwave treatment time on the organic sulfur were studied.And the rate of recovery and RSD of the method were calculated.Result] The results showed that the organic sulfur of samples was basically removed when the microwave treatment time was 60-90 s.The rates of recovery were in the range of 80%-120%,and RSD was less than 15% when different kinds of pesticides treated by different methods.Conclusion] The method is simple and rapid,and able to solve organic sulfur disturbance effectively in pesticide residue analysis. |
