Abstract

2, 4, 6 TRICHLOROPHENOL (TCP) is one of the most toxic chlorophenols which is very difficult to biodegradation. Advanced OXIDATION Processes (AOPs) is one of the most effective processes for degradation of persistent compounds. Since the mineralization of recalcitrant compound by AOPs often requires long reaction time and strong doses of oxidant, the combination of this process with biological one, is considered as an efficient and economic method. In this work degradation of 2, 4, 6 TRICHLOROPHENOL in aqueous solution with FENTON REAGENT (H2O2 +Ferrous ion) was studied. The experiment was done in batch mode, and the initial concentration of TCP was 0.60mM. In pH=3, H2O2=1.8mM, Fe=0.6mM, more than 99% of TCP was degraded in 10 minutes after the reaction was started. Chloride ion generation as TCP degradation by product was investigated, and it was found that the scavenging effect of chloride is negligible. PH and UV215 absorbance analysis, after reaction completion, indicated that generated intermediates had the less chlorinated nature, acidic properties and nonphenolic structure. Chloride ion increases from 0 mg/L to 40 mg/L, pH decreased from 3 to 2.7 and UV215 absorbance decreased from 3.2 to 0.6, therefore it can be resulted that their biodegradability modified and their recalcitrance reduced. COD analysis indicated that TCP did not mineralize and in H2O2/TCP = 3 and OXIDATION time of 1 h, COD reduction was only 37%.
