Dyes are an important class of pollutants which when discharged into water resources can be toxic to the aquatic environment and cause serious problems for public health. Various treatment technologies such as adsorption are in use. For this reason, clinoptilolite was used as a low-cost adsorbent to remove color from aqueous solution. Clinoptilolite was modified with sulfuric and phosphoric aci...
The effect of various parameters (pH, irradiation time, nanophotocatalyst dosages and temperature) on photocatalytic degradation of Direct Red 23 (DR 23) and Direct Brown 166 (DB 166) using pure InVO4 and InVO4-TiO2 nanocomposite were investigated under visible light irradiation. InVO4 and InVO4-TiO2 wer...

In this paper, dye removal ability of the surface modified nanoparticle SMN copper ferrite from single and quaternary systems was investigated. Acid Blue 92 AB92, Direct Green 6 DG6, Direct Red 23 DR23 and Direct Red 80 DR80 were used as model compounds. The effect of surfactant concentration, adsorbent dosage, dye concentration and pH on dye removal was evaluated. The adsorption isotherm and k...
In this work, the photocatalytic degradation of organic dyes was studied employing zinc oxide based nanocomposites. In this purpose, ZnO based nanocomposites were synthesized using three different procedures including co-precipitation, hydrothermal and combustion methods. The samples were characterized by SEM, XRD, IR and UV-Vis spectrophotometer. Afterwards, the prepared samples were utilized ...
