“…Some k values of photodegradation of dyes in photocatalysis without microwave irradiation are listed in Table 3. Compared to reported k values in the literature ranging from 0.39 to 5.085 mg/L/ min for dye pollutants [19,21,22,28e30], the value 8.9 mg/ L/min in TiO 2 /MWL appears higher. This indicates that microwave irradiation accelerates the reaction between X-3B and hydroxyl radicals.…”

“…Many researchers have used these processes, such as photocatalysis, electro-Fenton, wet-air [5,6], Fenton [7,8], and ozonation applications [9][10][11][12] to deal with this waste. Especially, ozonation has been one of the most effective oxidation processes.…”

In this study, the decolorization, dearomatization, and mineralization efficiencies of different advanced oxidation processes (AOPs; namely O 3 , O 3 /Fe(II), O 3 /Fe(II)/UVA, and O 3 /TiO 2 /UVA) were investigated for the azo dye C.I. Reactive Red 194 (RR194). The effects of pH (3-11), amount of TiO 2 (0.05-1 g/L), and concentration of Fe(II) (0.1-1.6 mM) were investigated for the applied methods. The decolorization and mineralization efficiencies of the photocatalytic ozonation system (O 3 /TiO 2 /UVA) were increased by decreasing the pH of the dye solution in contrast to the ozonation system (O 3 ). Decolorization of RR194 was increased in the photocatalytic ozonation system with an increasing amount of catalyst however, a decreasing was occurred for the homogeneous catalytic system (O 3 /Fe(II)) when increasing the concentration of catalyst. The decolorization efficiency of the homogeneous catalytic system (O 3 /Fe(II)) was enhanced when combined with UVA light. In our study, the most efficient method for dearomatization and mineralization was the O 3 /TiO 2 /UVA among the applied AOPs.

“…Mendez et al [31] investigated the cathodic decolorization of Remazol black B (20 to 80 mg/L) using a Ni-polyvinylchloride composite and reported almost complete color removal and no organic contaminant removal after one hour of treatment at -3.0 V vs. SCE. Erdal et al [32] studied the degradation of RB5 (Reactive black 5) at lower concentration levels (20 mg/L) using an electro-fenton method (carbon-platinum electrodes) in a batch setup and reported almost complete removal after 30 min of treatment. Rivera et al [33] studied the electrochemical degradation of RB5 using diamond and metal alloys electrodes in a batch recirculation setup and reported 95% color removal and 65 -67% COD (chemical oxygen demand) removal.…”

This study focused on the electrochemical degradation of hydrolyzed Remazol Black B (CI Reactive Black 5), a common diazo reactive dye, in aqueous solution. In the presence of various auxiliary dye chemicals, a typical Remazol Black simulated exhausted dyebath liquor was treated electrochemically in various basic electrochemical reactor configurations such as batch, batch recirculation and single pass systems. The effect of current density, supporting electrolyte concentration, electrolysis duration, specific electrode surface and fluid flow rate on pollutant removal and energy consumption performance of the systems was critically evaluated. Batch studies show the following operating parameters, current density: 2.5 A/dm 2 , electrolysis duration: 6 h, and supporting electrolyte concentration: 3 g/L, were optimal for good overall performance of the system. Color removal was complete by 3 h of treatment for all combinations of parameters studied. The pollutant removal performance of the batch recirculation system was found to have improved considerably by increasing the flow rate. Performance of the batch recirculation system was comparatively better than the other rector configurations studied, with respect to capacity utilization and energy consumption.
