摘要：The degradation of 2-chlorophenol (2-CP) by persulfate was investigated.The kinetics of persulfate oxidation of 2-chlorophenol in aqueous solutions at various pH, oxidant concentration, temperature, Fe2 and Cu2 ions content was studied.Maximum of 2-CP degradation occurred at pH 8.The oxidation rate of 2-CP increased with increasing the persulfate molar excess.The degradation process was significantly influenced by temperature – the higher temperature results in a faster degradation of 2-CP.The activation of persulfate by ferrous and copper ions was also studied.Results showed that persulfate is activated more effectively by iron(II) than copper(II) ions.A comparison of different persulfate activation methods revealed that heat-activation was the most effective.Under optimal conditions, in the presence of ferrous ions at 50 °C, complete degradation of 2-chlorophenol was achieved after about 30 minutes.
