Adsorption Rate of 198 Reactive Red Dye from Aqueous Solutions by using Activated Red Mud
Backgroud and purpose: Dye is one of the problems of industrial effluent such as textile industries. The dyes can be removed by various methods. Therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. Materials and methods: This research was a lab study. Activated red mud was used as an adsorbent to remove reactive r...
متن کاملAdsorption Kinetics and Equilibrium Studies of Reactive Red 198 Dye by Cuttlefish Bone Powder
In this research, the removal of Reactive Red 198 dye (RR-198) by Cuttlefish bone powder was investigated. The adsorbent was prepared in laboratory conditions and ground by ASTM standard sieves (60-100 mesh). The progress of the process is monitored spectrophotometrically by measuring the absorbance of dye at 518 nm wavelength. In addition, the effects of process parameter...
متن کاملInvestigation of affecting operational parameters in photocatalytic degradation of reactive red 198 with TiO2: optimization through response surface methodology
Dye-containing wastewater generated from textile industries is a major source of environmental pollution. Azo dyes, which are the largest group of coloring agents, are widely used in industries.This research investigated the photocatalytic decolorization and degradation of an azo dye Reactive Red 198 (RR198) in aqueous solution with TiO2-P25 (Degussa) as photocatalyst in slurry form using UV li...
متن کاملTiO2/Fe3O4 Nanocomposite Photocatalysts for Enhanced Photo-Decolorization of Congo Red Dye
TiO2 /Fe3O4 nanocomposites with various TiO2:Fe3O4 ratios were synthesized by an ultrasonic-assisted deposition-precipitation method and their UV-light decolorization of Congo dye and magnetic separation were investigated. The nanocomposite samples were characterized by scanning electron microscopy (SEM), powder X-ray diffraction (XRD), surface area analayzer (BET) and Fourier transform infrare...
متن کاملDECOLORIZATION OF A TEXTILE DYE, REACTIVE RED 198 (RR198), BY Aspergillus parasiticus FUNGAL BIOSORBENT
The decolorization potential of textile dye Reactive Red 198 (RR198) by Aspergillus parasiticus fungal biosorbent has been investigated as a function of initial pH, contact time, biosorbent and initial dye concentration in a batch system. Maximum dye biosorption capacity 1.03x10 mol g was observed at pH 2.0 and 2.0 g L of biosorbent concentration. Biosorption equilibrium was attained within 50 ...
