To establish a method for determination 9 organochlorine pesticide residue in Microcos paniculata by gas chromatography.
The sample was infiltrated with water and extracted with hexane by ultrasonic. The extract solvent was purified by concentrated sulphuric acid. DB-1701 capillary column was used to separate the sample. GC-ECD was applied to determine the residues of organochlorine pesticide.
The percentage recoveries were ranged from 78.1% to 97.8% and RSD were from 2.4% to 8.8%.
The method established is quick, simple and low in cost.
