Electrocoagulation induced treatment of indigo carmine textile dye in an aqueous medium: the effect of process variables on efficiency evaluated using biochemical response of Gammarus pulex

In this work, a composite consisting of bovine bone powder impregnated with Fe(III) ions was prepared and its performance evaluated as a catalyst for the degradation of the textile dye Indigo Carmine in aqueous medium. One of the advantageous features of this new material is that it is inexpensive, simple to prepare and the support, bovine bone, is one the final residue of food production. The material was fully characterized by X-ray powder diffraction (DRX), 57Fe-Mössbauer spectroscopy, surface area measurements (BET), atomic absorption spectrometry. The degradation of Indigo Carmine was monitored by ultraviolet spectroscopy in the visible region (UV-Vis) and the by-products characterized by direct infusion ESI(-)MS (electrospray ionization mass spectrometry in the negative ion mode).

Indigo Carmine Dye

The present paper discusses an integrated electrochemical decolorization/degradation treatment procedure of indigo carmine dye, which comprises electrocoagulation, electrooxidation and advanced electrochemical oxidation using the electro-Fenton process. The electrocoagulation process is performed by sacrificial iron electrodes, the indirect electrooxidation process by dimensionally stable Ti/Pt and graphite electrodes in NaCl electrolyte solution, and the electro-Fenton process by iron electrodes and added amounts of H2O2. All electrochemical experiments are conducted in the same electrochemical cell with the same apparent electrode surface and inter-electrode distance. <div> The three different electrochemical processes are discussed, their efficiencies compared and evaluated. The initial dye concentration of 100 mg l-1 was fast and efficiently removed in only a few minutes of electroprocessing time. The electro-Fenton treatment is the fastest, most efficient and economical process operated at very low current densities of 0.33 and 0.66 mA cm-2 and consuming only 4.75x10-3 and 5.23x10-3 kWh m-3 of treated solution respectively. The electrocoagulation treatment with iron electrodes and the electrooxidation process with Ti/Pt electrodes conducted at applied current densities of 5 mA cm-2 consumed 0.511 and 0.825 kWh m-3 of treated solution respectively. The proposed procedure is a safe, economical and efficient method for removal of indigo carmine dye from aqueous solutions and dye house effluents. </div>

AbstractBox-Behnken design was employed for the decolourization of synthetic dye bath effluent using solar induced photo catalytic degradation with mixed semi conductor catalysts. Four independent variables namely concentration of dye effluent, catalyst loading, pH and irradiation time was chosen as process variables. The optimum concentrations of dye effluent, catalyst dosage, pH, and irradiation time were found to be 60 mg L−1, 200 mg L−1, 7 and 100 min, respectively, for maximum decolourization of dye effluent (91.24%). Predicted values were found to be in good agreement with experimental values and as a result reflected the precision and the applicability of Response Surface Methodology (RSM) (R2=0.9785 and Adj R2= 0.9569).
