Background: Advanced oxidation processes are used to remove toxic aromatic compounds with low biodegradability, such as 2-chlorophenol. This study investigates the use of Sulfate (SO4-) and persulfate (S2O82-) radicals, as one of the advanced oxidation methods, to remove 2- chlorophenol from aquatic solutions.

Materials and Methods: This experimental and pilot-scale study was carried out using two chemical batch reactors one of the reactors equipped with UV lamps and the other was on the hot plate. In Iron/ Persulfate (Fe/S2O82- ) and Ultra violet/ Persulfate (UV/S2O82- ) processes different parameters were investigated.

Results: The results show that iron, UV, the initial pH of the solution, persulfate concentration have considerable effects on the elimination of 2-chlorophenol in both processes. In both processes, the maximum elimination occurred in acidic conditions. The elimination efficiency increased by increasing the concentration of 2-chlorophenol and UV intensity, and also by decreasing the concentration of persulfate and iron. Accordingly, in Iron/ persulfate and Ultra violet/ persulfate processes 2-chlorophenol was eliminated with 99.96% and 99.58% efficiencies, respectively.

Conclusion: Sulfate radicals which are produced from activated persulfate ions with hot-Fe ion and UV radiation have significant impact on the removal of 2-chlorophenol. Therefore, the processes of Fe/S2O82- and UV/S2O82- can be regarded as good choices for industrial wastewater treatment plants operators in the future.

Keywords: 2-Chlorophenol, Iron, Persulfate, Radical Sulfate, UV Radiation
