A study of the ozonation of the herbicide alachlor in distilled and surface water was performed. The influence of variables, including pH, water type, and free-radical-inhibiting substances, on the removal rate of alachlor was investigated. Alachlor was primarily removed from water through hydroxyl radical oxidation because low pH and the presence of natural substances such as carbonates significantly reduced the alachlor removal rate. Hydrogen peroxide was formed in low concentration during ozonation. Rate constants of the reactions between alachlor and ozone and between alachlor and the hydroxyl radicals were found to be 2.8 and 3.2 × 1010 L/mol·s, respectively. Because combined UV radiation and ozonation constitute one of the possible ozonation processes to treat alachlor, the quantum yield of this herbicide was determined and found to be 0.177 mol/einstein, which is a significant value compared to others found for different herbicides.
