| A method for determining endosulfan and its metabolin in surface water was established by using GC/MS with NCI, hexane as extractive solution, quantization by external standard method. Linearties of calibration curve of α-endosulfan, β-endosulfan and endosulfan sulfate were good in range from 0.200 μg/L to 10.0 μg/L,the method detection limits 0.010 μg/L, 0.008 μg/L and 0.010 μg/L respectively for the three compounds, RSD of blank and spiked duplicates from 3.9% to 4.8%, spiked recoveries of surface water samples from 85.5% to 93.8%. |
