Removal of acid dye by ZnFe2O4/TiO2-immobilized granular activated carbon under visible light irradiation in a recycle liquid–solid fluidized bed

Environmental Bioremediation of Dyes by <i>Pseudomonas </i><i>a</i><i>eruginosa </i>ETL-1 Isolated from Final Effluent Treatment Plant of Ankleshwar

“…Though neutral pH 7 was best for degradation of the dyes, pH 9 appeared to be well tolerated and significant amount of dye could be degraded at that pH, thus indicating the potential of this organism to degrade dyes over a range of pH. Tolerance to varying pH by dyedecolorizing bacteria is quite important, as it makes them suitable for practical biotreatment of dyeing mill effluents [37,54]. However, to achieve the best rate of degradation, it is suggested that the pH of textile effluents be neutralized to 7.…”

High efficiency reductive degradation of a wide range of azo dyes by SiO 2 -Co core-shell nanoparticles

“…Chemical treatment for dye degradation, on the other hand, is considered efficient and fast [22][23][24][25][26][27][28][29][30][31][32]. Among different chemical treatments, use of zero-valent metals such as iron [33][34][35][36], ironnickel alloy [37] and cobalt [2], respectively, as reductive catalysts, are showing both the effectiveness and eco-friendliness needed for efficient dye degradation.…”

AC/TiO2/Rubber Composite Sheet Catalysts; Fabrication, Characterization and Photocatalytic Activities

“…Although the traditional treatment methods such as chemical coagulation, activated sludge, trickling filter and carbon adsorption have been widely utilized for decolorization of dyes but which have difficulties in the destruction of dye pollutants due to their complex structure, most of dye are recalcitrant [1,2]. In the pastfew decades, the applications of heterogeneous photocatalysis using semiconductor materials for environmental protection, purification and remediation have been attracted much attention [3].…”
