Adsorption of Reactive Red 194 Dye from Textile Effluent by Using Class F Fly Ash
نویسندگان
چکیده
A low cost adsorbent Fly Ash was used for the removal of Reactive Red 194 dye (RR 194 dye) from textile effluent. The Fly ash was activated by chemical treatment by N/2 H2SO4. Batch adsorption experiments were performed as functions of adsorbent doses, initial dye concentration, contact time, and pH. The percentage of colour removal was increased with decreasing dye concentration and increasing contact time and adsorbent doses. Maximum removal of colour has been taken place in acidic medium (pH=5). Adsorption data was fitted on Langmuir and Freundlich Isotherm modal. From the experimental data it was found that the adsorption process using fly ash adsorbent could be well described by Langmuir modal than the Freundlich modal.

متن کاملRapid Adsorption of Crystal Violet onto Magnetic Zeolite Synthesized from Fly Ash and Magnetite Nanoparticles
This work reports the adsorption of crystal violet (CV) dye onto magnetic zeolite (MZ) nanoparticles, synthesized by direct fusion of fly ash (FA) and magnetite particles. The synthesised MZ showed high capacity for CV dye adsorption, removing 95% of the dye at an equilibrium adsorption time of 10 min and 25 ̊C. The effects of adsorbent dosage, dye concentration, and pH, on adsorption were evalu...
متن کاملApplication of Multi-Walled Carbon Nanotubes in the Removal of Reactive Red 120 from Aqueous Solutions
Background and purpose: Textile effluents are very difficult to treat satisfactorily due to high variations in their compositions. Strong color is one of the main characteristics of textile effluent and, if not eliminated, it can cause serious problems to the environment. In the present study, multi-walled carbon nanotubes (MWCNTs) were used as an adsorbent for the removal of Reactive Red-120 (...
متن کاملUtilization of Fly Ash as Low Cost Adsorbent for Treatment of Textile Dying Industry Effluents: Kinetics and Isotherms
Abstract--Textile dying industry effluents are highly toxic in nature and it contains a large number of complex metal dyes. Many dyes used in textile industries are stable to light and resistant to aerobic digestion. Thus removal of coloured waste from industrial dye effluent is a most perplexing problem to such industries and the environment. On the other hand fly ash is a major pollutant gene...
