In this way, the search for cheaper and efficient adsorbents, such as, low-cost agricultural wastes, to replace activated carbon has gained attention in recent years [12].…”

“…Several traditional treatment processes have been applied for the removal of MB dye from waters and wastewaters in order to decrease their impact on the environment. The processes developed consist basically in decolorizing by electrochemical combined with biological treatment [4], photocatalytic oxidation [5], Fenton treatment [6], nanofiltration [7], sonocatalytic degradation [8], biological treatment [9], and adsorption on activated carbon [10]. Activated carbon is most popular adsorbent used for metals, pesticide, and dye removal.…”

In this study, Punica granatum husk (PGH), an agricultural powdered biowaste, was used as adsorbent for the removal of methylene blue (MB) dye from aqueous solutions. The effects of initial pH of solution, adsorbent dosage, contact time, and initial dye concentration on the MB adsorption were evaluated in batch adsorption mode at 298 K. Kinetic data were evaluated by pseudo-first-order, pseudo-second-order, and Elovich models. The equilibrium adsorption was evaluated by Langmuir, Freundlich, and Sips isotherm models. The applicability of PGH was also evaluated for simulated effluents. The results revealed that pseudosecond-order model agreed well with the experimental kinetic data. The adsorption of MB onto PGH was better fitted using Sips isotherm. The maximum adsorption capacity obtained by Sips model was 68.40 mg g −1 . Regeneration of PGH adsorbent was possible using 1.0 mol L −1 of HCl as eluent. PGH adsorbent is adequate for removal of MB from simulated textile and river effluents. The results obtained in this work show that PGH can be used as alternative adsorbent for MB removal from effluents.

“…In these industries, large amount of MB with usual concentration of 10–200 mg L −1 is discharged in the effluent streams . The colored effluents are known for unfavorable effects on natural ecosystems and aquatic life such as the obstruction of light penetration, decrease of the dissolved oxygen, and mutagenic effects . European communities regulation for discharge into surface waters is 0.2 mg of MB in each liter .…”

Aerobic degradation of methylene blue by a pure culture of Ralstonia eutropha was studied by both freely suspended cells and kissiris‐immobilized packed bed reactors. Kissiris as a cell support matrix favored the retention of the cells in the packed bed reactor during of the methylene blue biodegradation process. The biodegradation experiments showed that the kissiris‐packed bed reactor had higher performance in removal of the dyestuff for initial concentrations equal or higher than 150 mg L−1 when compared with the freely suspended cells. To evaluate the effect of mass transfer phenomena in the immobilized system, mass balance of methylene blue for a single kissiris piece was applied to derive expressions correlating the methylene blue concentration in the bulk liquid medium and inside of the bioparticle. Kinetics studies revealed a self‐inhibitory effect of methylene blue on its biodegradation at concentrations higher than 85.76 mg L−1 in the free cell and 190.1 mg L−1 for immobilized system. The mass transfer modeling indicated the protective role of the support from cells against the inhibitory role of methylene blue is related to both external and internal mass transfer limitations in the immobilized system. In the kissiris packed bed reactor, the effectiveness value was higher than unity for initial methylene blue concentration of 150 mg L−1.

The influence of cathode material on the electrochemical degradation of methyl orange (MO), methylene blue (MB) and malachite green (MG) dyes was investigated. The cathode materials used were platinum (Pt), copper (Cu), zinc (Zn) and aluminum (Al). The electrochemical activity of the selected dyes on the metal cathodes was examined by cyclic voltammetry (CV). The electrochemical treatment was carried out in both divided and undivided cells. The degradation process was monitored by UV-Visible spectroscopy and chemical oxygen demand (COD) measurement. The influence of pH on discoloration and degradation of dyes was studied. The power consumption and current efficiency of the treatment process involving different cathode materials was computed and compared. The role of cathode material in the degradation of dyes has been established.
