چکیده

In a batch reactor, the EF advanced oxidation decolorization of aqueous solutions methyl orange MO, commercial azo reactive textile dye, was investigated in presence two different electrodes. The evaluation included various operational variables such as IC current intensity (60 mA, 80 and 100 mA), initial concentration pollutant MO (20 mg/L, 40 60 mg/L), pH solution (3, 5, 7), temperature °C, 30 50 °C), catalyst [Fe2+] (0.1 mM, 0.2 0.3 mM) on discoloration rate. A Box-Behnken Design Experiment (BBD) used to optimize parameters that directly affect Electro-Fenton (EF) process. Under optimal experimental conditions = 0.232 3, [MO] T ± 0.1 maximum rate achieved 94.9%. during treatment time confirmed by analysis UV-visible spectrum. After review literature organic degradation, system provided here is shown be one best terms when compared other AOPs.

Decolorization of Methyl Orange (As a Model Azo Dye) by the Newly Discovered Bacillus Sp

A bacterial strain (strain PS) was isolated from the textile effluents carrying Serilene Black BNFS® (C.I. Disp. Blk. Mix) disperse dye. The isolate was able to decolorize the dye without the need for any exogenous carbon source. Full sequencing of its 16S rRNA indicated that Bacillus sp strain PS is related to Bacillus cereus groups.  Silica- gel-thin layer chromatography of Ser...
