摘要

A kinetic model that describes the removal of organic pollutants by an ozone/UV process is described.Oxalic acid,which reacts with a very low rate constant with ozone and relatively high rate constant with hydroxyl radical (OH~centre dot),was used as the probe chemical to model the process.The model was verified by experimental data on concentrations of oxalic acid and hydrogen peroxide (H_2O_2) under various experimental conditions,i.e.,ozone gas dosage,UV light intensity,and varying oxalic acid concentrations.
