Abstract: | Using 1∶1 acetone-n-hexane as extraction solvent,adding activated carbon and aluminum oxide neutral to the samples are comlpeted the vortex mixing,ultrasonic oscillation and extracted-cleaned up the samples at the same time.The paper provide the methods of rapid determination of five usual organophosphorous pesticides in farmaland soil using gas chromatography GC-NPD.The recovery of this method can reach 85%~95%,the precision is less than 8% and the detection limits are 0.2 ng/g~1.8 ng/g. |
