| Abstract: | A method was established for determining dimethoate in tea drinks.Samples were extracted with acetonitrile,concentrated after salting out,and determined by gas chrormatography(GC).Under these conditions,the average recoveries in different addition levels of dimethoate were 82.40%～108.65%,the relative standard deviations were 2.30%～8.15%.The method is simple,rapid and sensitive.It is applicable to the determination of dimethoate in tea drinks. |
