Degradation of 4-nitro phenol by ozone and determine the rate reaction
Author(s):
Abstract:
One of the most effective methods for degradation of aromatics is advanced oxidation processes, such as ozonation. The model compound was 4-nitro phenol that carried carried at pH (3), (7) and (9) under ozonation during 30 min. Ozonation of 4-nitro phenol was occurred where the Ozone concentration can be considered constant and analysis of concentration, UV Absorbance, COD and TOC and NO3- ions was mentioned during ozonation. Result show that the highest removing rate of 4-nitrophenol achieved at alkaline conditions, i.e., the indirect mechanism of hydroxyl radical attack on 4-nitro phenol. Among the by-products formed during the ozonation of 4-nitrophenol formed during ozonation was quinine.
