Title: Study on the Determination of Prometryne Residues in Environment
Abstract: A method for the determination of prometryne in soil,water and wheat of environment was developed by HPLC.Residue in soil was ultrasoniclly extracted with acetone,followed by cleanup with a silica gel column;residue in water was purified by LC-18 SPE column;and residue in wheal was ultrasoniclly extracted with a mixture of V(methanol)∶V(water)=1∶1 which was then adjusted to a volume with distilled water and passed through a LC-18 SPE column.The extracts of three samples were analysed by HPLC-UVD.The correlation coefficients(R2) of this method was 0.9999,and their calibration curves were linear in the range of 0.5~16 mg·L-1 with the detection limit of 0.0125 mg·L-1.The recoveries ranged from 88.2% to 102.4% for soil,81.7% to 102.5% for water and 88.4% to 101.7% for wheat,with the RSD of 6.3%~6.4%,4.5%~4.6% and 3.6%~5.5%,respectively.
