Abstract
In this study, a series of experiments were conducted using a standard solution containing α and β-endosulfan.to folow the.for residual pesticides was established by a gas chromatography equipped Ultra II[(30 m. 0.25.mm(ID). 0.25m] capillary column and a -electron capture detector(-ECD). Recovery rates of residual pesticides for soilsamples were 96-100%. The amount of α and β-endosulfan that was spread in the soil was checked for variousperiod of time. It indicated that the amount was reduced to 73 and 61%, respectively. When the water spreadamount increased from 10 to 100 mL, α-endosulfan was eliminated from 45 to 85% and while β-endosulfan from44 to 88%. Removal rates of α-endosulfan and β-endosulfan were 99% and 98% respectively within 30 minutes.It was assumed that the organic salts and strong alkali elements contained in the pesticide degradator hydrolyzedthe residual pesticide.
