Fenton's Reagent

Oxidations using Fenton's reagent have not been followed previously by redox titration. This procedure assists in defining the overall reaction and allows both an estimate of relative rates of oxidation and a measure of the consumption of peroxide by the organic substrate. The peroxide consumed in the complete oxidation of substrate to inactive compounds has been measured by titration at constant oxidation potential. Such measurements reflect the peroxide consumed by the substrate and its consecutive oxidation products and may therefore be used to assess the significance of oxidation pathways.

Oxidation Of Ethanol

The oxidation of ethanol by Fenton's reagent was studied to confirm the validity of the redox titration procedure. A quantitative analysis of oxidation products during the complete oxidation of ethanol and its consecutive oxidation products is presented. � The oxidation of t-butyl alcohol was studied under a number of different conditions and yields of acetone and the dimer, 2,5- dimethylhexane-2,5-diol, were obtained. The effects of oxygen, copper salts, and chloride and bromide ions on this oxidation were studied. ��� The ratio of reaction rates of ethanol and t-butyl alcohol with the free hydroxyl radical was determined.

Congo red is a toxic azo dye which is used extensively in industries like textile, paper, pulp and paper. Very high amount of Congo red from these industrial sources is discharged into natural water bodies resulting environmental pollution. The present work reports the kinetics and mechanism of oxidative decomposition of Congo red by Fenton’s reagent in homogeneous medium and also under ultra violet light irradiation. Kinetic parameters like effect of [Fe2+], [H2O2], [Congo red] and temperature on the decomposition of Congo red were studied. The reaction is found to be fractional order with [Fe2+] and first order with [H2O2] and [Congo red]. The rate of oxidative decomposition of Congo red by Fenton’ reagent showed a rapid increase of three times when irradiated with ultra violet radiation and completion of reaction occurred within 5-6 minute. Various thermodynamic variables were determined and the presence of isosbestic points on sequential scanning of oxidation kinetics proves that the reaction is very smooth, spontaneous and endothermic. A suitable mechanism is suggested based on the experimental results obtained.

Removal Efficiencies

This study was designed to use both artificial and real textile secondary effluents to evaluate (1) the COD and color removal efficiencies for ferrous coagulation and Fenton's coagulation, and (2) the feasibility of using hydrogen peroxide to improve ferrous coagulation to meet more stringent effluent standards. The results indicate that the optimum pHs for both ferrous coagulation and Fenton's preoxidation processes range between 8.0–10 and 3.0–5.0, respectively. The rate for color removal is faster than that for COD removal in the Fenton's preoxidation process. The removals of COD and color are mainly accomplished during Fenton's preoxidation step. The ratio of COD removal for Fenton's coagulation versus ferrous coagulation, given the same ferrous dosage, ranges from 1.4 to 2.3, and it ranges from 1.1 to 1.9 for color removal, using two effluent samples. Therefore, using hydrogen peroxide can enhance the ferrous coagulation, and this ensures more stringent effluent standards of COD and color are met.
