ADSORPTION AND LEACHING OF 1-(2-CHLOROBENZOYL)-3-(4-CHLOROPHENYL)UREA(CCU)
灭幼脲Ⅲ号在土壤中的吸附与淋溶

Adsorption of l-(2-chlorobenzoyl)-3-(4-chlorophenyl) urea (CCU) in four different soil samples was studied with a batch equilibrium method in laboratory conditions. Freundlich adsorption constants and adsorption isotherm curves were obtained.Leaching of l-(2-chlorobenzoyl)-3-(4-chlorophenyl) urea in different soil columns was also studied. The experiment results indicated that the movement of the compound in soils was slow.
