摘要

A determination method for dinotefuran residue in paddy plants,brown rice,husk,soil and paddy water was established using high performance liquid chromatography(HPLC).The simples of brown rice,plants,and soil were extracted with acetonitrile+ammonia solution,while the simple of husk was extracted with dichloromethane+ammonia solution.After liquid-liquid extraction,the solutions were concentrated and set to constant volume,and then quantified by external standard method.The results showed that when the adding level ranged from 0.01mg/kg to 1.0mg/kg,the average recoveries of dinotefuran in rice plants,brown rice,husk,soil and water were 86.4%-99.3%;the relative standard deviations were 0.44%-3.60%,and the minimum detectable concentration was 0.01mg/kg.
