| Abstract: | The determination method of carbendazim residues in groundwater by SPE- HPLC was studied. The samples were processed by C18Solid- Phase Extraction( SPE) column,with mobile phase of methanol-( water and ammonia),high- performance liquid chromatography- UV detector and the residues were quantified external standard calibration curve method. The linearity was kept in the range from 0. 01—1. 0 mg / L,with correlation coefficient0. 999 9. The limits of detection was 0. 003 4 mg / L. The recovery studies were performed at the three spike levels of0. 01,0. 05 and 0. 18 mg / L,the mean recoveries were between 95. 3% and 97. 8% with a relative standard deviation( RSD) ranging from 3. 09% to 4. 18%. The method was practicably analysing the actual sample,and it was suitable for detecting trace of organisms in groundwater. |
