- Removal of water soluble Reactive Black KN-B from aqueous media by means of titanium dioxide/attapulgite (TiO2/ATP) composites was studied in a batch system. The composites were investigated using X-ray diffraction and surface area analysis. Under UV irradiation, the photocatalytic effect of TiO2/ATP composites, pH and reaction temperature on the decolorization rate of Reactive Black KN-B were investigated in detail. The adsorption experiments of TiO2/ATP composites showed that the isotherms and adsorption kinetics were well followed by the Langmuir model and the zero order equation, respectively. The maximum adsorption capacity of TiO2/ATP composites for Reactive Black KN-B calculated by the Langmuir model was 20.08 mg g-1. It can be concluded that the TiO2/ATP composites could be good photocatalysts/adsorbents for treating Reactive Black KN-B wastewater.
