en 2-Chlorophenol Removal of Aqueous Solution Using Advanced Oxidation Processes Resulting from Iron/ Persulfate and Ultra Violet/ Persulfate تخصصي Special كاربردي Applicable <p dir="ltr"><strong>Background: </strong>Advanced oxidation processes are used to remove toxic aromatic compounds with low biodegradability, such as 2<strong>-</strong>chlorophenol. This study investigates the use of Sulfate (SO₄^-) and persulfate (S₂O₈^2-) radicals, as one of the advanced oxidation methods, to remove 2- chlorophenol from aquatic solutions.</p> <p dir="ltr"><strong>Materials and Method</strong><strong>s</strong>: 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/S₂O₈^2- ) and Ultra violet/ Persulfate (UV/S₂O₈^2- ) processes different parameters were investigated.</p> <p dir="ltr"><strong>Result</strong><strong>s</strong>: 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.</p> <p dir="ltr"><strong>Conclusion</strong>: 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/S₂O₈^2- and UV/S₂O₈^2- can be regarded as good choices for industrial wastewater treatment plants operators in the future.</p> 2-Chlorophenol, Iron, Persulfate, Radical Sulfate, UV Radiation 1 8 http://ijt.arakmu.ac.ir/browse.php?a_code=A-10-219-2&slc_lang=en&sid=1 Shokufeh Astereki شکوفه آسترکی 100319475328460011175 100319475328460011175 No Department of Environment Health, Lorestan University of Medical Sciences, Khoramabad, Iran.
