Optimization of Gas Chromatography-Mass Spectrometry for the Determination of Benfuracarb in Rice
In this study,based on SN/T 2915-2011,the determination method of propoxur in rice was optimized,and the key steps of sample pretreatment were improved.After optimization,the sample pretreatment process became more simple,and the loss in intermediate transfer process was reduced,the detection of propoxur in rice was more accurate and efficient,the relative standard deviation was lower than the original method,and the recovery rate of spiked samples was 80.0%to 98.5%.
