چکیده انگلیسی
The radiation-induced degradation of acetochlor was investigated in this work. In a mixed solvent composed of acetonitrile and water at a ratio of 20/80 in volume, the acetochlor degradation rate was proportional to the radiation dose rate and acetochlor concentration. The acetochlor degradation efficiency was higher under alkali conditions and lower under acidic conditions. The contribution to the acetochlor degradation by the radicals was in the order of: eaq->OH>H. The quantum efficiency ratios of OH, eaq- and H for the degradation of acetochlor were calculated as 1:3:1.
