Chemical Oxidative Degradation of Acridine Orange Dye in Aqueous Solution by Fenton's Reagent

The removal of acrylonitrile by Fenton-precipitation and Fenton-microfiltration was investigated in this study. As for Fenton-precipitation, in the range of pH 2 to pH 4, TOC removal efficiency decreased with the increase in pH during the Fenton-precipitation of acrylonitrile. Fenton-microfiltration had a significant improvement on TOC removal at pH 3 and 4 as compared with Fenton-precipitation. The highest removal efficiency of 95% was obtained at pH 3 and the solution pH value had a significant effect on the total permeate quantity and the rate of accumulation. Experimental results led to the conclusion that the oxidation caused by Fenton's reagent was predominant at pH 2. On the contrary, coagulation was most significant at pH 3 and 4. The results indicated the superiority of the Fenton-microfiltration process as compared with Fenton-precipitation process for the removal of acrylonitrile from water.

High Yields

Abstract Oxidation of substituted imidazoles with modified Fenton's reagent (Fe(II), ascorbic acid, EDTA and H2O2) in aqueous solution at pH 5-7 in the presence of inorganic ortho-phosphate gives high yields of an unknown bound phosphate, in the case of 2-methyl-imidazole up to 35% based on inorganic phosphate. The dependence of the yields on reaction parameters and the hydrolytic behaviour of the compound was studied. The products are unstable in alkaline medium and fairly stable in acid solution (half-life period ca. 1 h at 25 °C in 1 N perchloric acid). Similar bound phosphate was also observed using autoxidation with O2 instead of H2O2.

The degradation of rhodamine B (RB) in aqueous solution by Fenton’s reagent was studied. After 30 min, the 96.2% removal of RB in water (pH = 3.0, T = 25 °C) was achieved when the initial concentrations of Fe2+, H2O2 and RB were 0.5 mM, 5 mM and 10 mg/L, respectively. A higher initial concentration of Fe2+ and H2O2 resulted in a higher efficiency in RB discolorization. The removal of RB was dependent strongly on the pH value of solution. Increasing the reaction temperature was beneficial for the RB degradation. Based on the Arrhenius equation, the activation energy (Ea) was calculated to be 16.78 kJ/mol from rate constants at different temperatures. The degradation of RB by Fenton’s reagent was inhibited by the presence of oxalic acid.
