The ozonation of herbicide 2,4-dichlorophoxyacetic acid (2,4-D) was studied and modeled at different initial pH levels and initial concentrations. The degradation rate of 2,4-D was found to increase with the initial pH level and decrease with initial 2,4-D concentration. A two-stage ozonation of 2,4-D was observed, in which the initial stage of ozonation was slightly faster than the second stage due...
