Abstract
An analytical method for determination of cinmethlin residue in rice (including unpolished rice, husk, straw and seeding), soil and water in rice field by GC/MS has been established. The cinmethlin residue in sample is extracted with acetonitrile (or acetone) and cleaned up by solid phase extraction(SPE) and then detected by GC/MS. The sensibility of instrument is less than 50pg. The minimum detectable level on cinmethlin in sample is 0.005mg/kg with average recovery rate of 80.0%～96.4% under different concentrations and variation coefficient of less than 13%. The application of the method in the determination of cinmethlin residue in various kinds of samples is satisfactory during cinmethlin residue test on rice corps.
