Abstract: 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.
