Abstract: | A GC-μECD method is developed to detect, wittier. After target compound extracted by CHCl2, extracted solvent is changed to acetone. Atrazine is separated with HP-5 10m×0.32mm×0.25μm column ,detected by ECD detector. The experiment result shows good resolution and high sensitivity. The MDL is 0.0002mg/L, and recovery rate of spiked sample ranges from 82.3% to 90.0%. So this method can meet the require of China Surface Water Quality Standard (GB3838-2002). |
