Experimental and modeling study of the adsorption of single and binary dye solutions with an ion-exchange membrane adsorber

Photocatalysis by morphologically tailored mesoporous silica (SBA-15) embedded with SnO 2 nanoparticles: Experiments and model

“…Discharge of effluents with dyes is undesirable, not only in terms of the persisting nature of colour, but also harmful to human beings because some of the dyes are reported to be toxic, carcinogenic and mutagenic [3][4][5]. Most common techniques to remove dyes from wastewater are adsorption on activated carbon, reverse osmosis, coagulation by chemical agents, and ultrafiltration [6][7][8][9][10][11].…”

High temperature synthesis of interfacial functionalized carboxylate mesoporous TiO2 for effective adsorption of cationic dyes

“…The numerous methods used to treat dye -loaded effluents can be divided into three categories: chemical (e.g., oxidation, photochemical), physical (e.g., adsorption, membrane filtration, ion exchange) and biological (e.g., aerobic and anaerobic biodegradation) [6][7][8][9]. Among them, adsorption has been found to be superior to others in terms of its simplicity, low cost, acceptable removal efficiency and ease of operation.…”

Microalgae Immobilized by Nanofibrous Web for Removal of Reactive Dyes from Wastewater

“…To evaluate the effects of operation factors on the efficiency of decolorization, the batch decolorization experiments were carried out at different contact time (0−14 days) and initial dye concentrations (10,25, and 50 ppm). After the inoculation process, aliquots (4 mL) of the culture media were withdrawn and centrifuged at 10 000 g for 10 min to separate the microalgae mass.…”
