AB  - Compounds used in the fashion industry effect the water bodies in the vicinity of textile factories, resulting in the visible coloration of surface water. Fe-doped graphite-based in house prepared electrodes were used in the Fenton- -like degradation of Reactive Blue 52 (RB52). The electrodes consisting of high-density graphite in three granulation sizes and three levels of Fe content were characterized using scanning electron microscopy (SEM). The amount of Fe in the electrodes and H2O2 concentration in synthetic textile wastewater were optimized. Additionally, the size of graphite grains was varied to investigate whether it effects the degradation rate. Under only 10 min of electro-Fenton degradation, a system with 10 mmol dm-3 of H2O2 and an electrode made of 7 % of Fe and 70 μm of granulation size of graphite, degraded over 75 % of RB52, and over 99 % after 40 min of treatment. The obtained results indicate that the proposed approach could be beneficial in the field of novel materials for environmental application and that in house prepared carbon could be an excellent replacement for commercially available supports.

AB  - The textile industry is one of the major pollutants of waterbodies with effluents high in biochemical and chemical oxygen demand values, high values of total dissolved solids, total suspended solids, and low dissolved oxygen values along with strong color. The existence of a successful method for its decontamination would be beneficial. In this work, we synthesized sponge-like europium oxide (Eu2O3) using a template-directed route from carbon hollow spheres, obtained from glucose as a carbon source. The material synthesis method was done in an aqueous environment, without using any organic solvents. Electrochemical properties of the synthesized material were investigated using cyclic voltammetry and electrical impedance spectroscopy, while morphological characterization was done using scanning electron microscopy and X-ray powder diffraction analysis. Eu2O3 were successfully immobilized at the surface of a screen-printed carbon electrode (Eu2O3/SPCE) using the drop-casting method. Finally, the prepared electrodes were tested toward the removal of Reactive Blue 52 (RB52) using electrochemical advanced oxidation processes (EAOPs). Important parameters, that is, the supporting electrolyte, its concentration, pH value, and the applied voltage, were optimized for RB52 degradation. The rate of removal was monitored spectrophotometrically and by high-performance liquid chromatography with a diode array detector (HPLC-DAD). It was found that the proposed approach reaches complete decolorization of the RB52 solution after a 60-min treatment, at pH 5.6 of KCl supporting electrolyte at a concentration of 0.05 M. Under optimal parameters, after 3 h of treatment, total organic carbon (TOC) was lowered by ~40%. The obtained results indicate that the proposed method may find potential application in EAOPs, considering electrode stability, durability, and efficiency and simplicity of the method.

AB  - Electrochemical degradation procedure for the removal of organic dye Reactive Blue 52 using nano-magnetite-doped carbonaceous electrodes was proposed. The electrode was prepared by calcination of graphite grains mixed with phenol–formaldehyde binder modified with iron nitrate. The morphology and phase composition of the electrodes were investigated using scanning electron microscopy and powder X-ray diffraction. Electrochemical degradation was done in Nafion membrane-divided cell where anodic part was filled with color solution and cathodic with supporting electrolyte. Parameters affecting on decolorization rate were investigated. A high increase in the removal efficiency, under optimized parameters, was noticed using carbon electrodes containing 1 mass% of magnetite in the presence of 3 mM hydrogen peroxide and 7 mass% of magnetite in the presence of 10 mM hydrogen peroxide. Almost 100% decolorization was achieved during 30 min with 62–77% of the mineralization. Based on these results, it can be concluded that this approach offered green, cheap and efficient degradation of reactive dyes and could be used as promising candidate for wastewater processing in the textile industry.
