The Removal of colour from aqueous solution include textile dyes

ABSTRACT Master Thesis THE REMOVAL OF COLOUR FROM AQUEOUS SOLUTION INCLUDE TEXTILE DYES Zeynep Eren Atatürk University Graduate School of Natural and Applied Sciences Department of Environmental Engineering Supervisor: Asst.Prof.Dr. Filiz Nuran Acar In this study, the adsorption of Chemazol Black B and Chemactive D Black N textile dyes on Soma fly ash, Elbistan fly ash and activated carbon has been investigated during a series of batch adsorption experiments. The effectiveness of fly ashes and activated carbon in adsorbing dyes from aqueous solutions has been studied as a function of agitation time, adsorbent dosage, initial dye concentration and pH. The equilibrium adsorption capasity of absorbents for textile dyes was obtained by using Freundlich and Langmuir isotherms. A maximum removal of 100 % was obtained at pH=l for an adsorbent dose of 1 g/L of 50 mg/L Chemazol Black B concentration on activated carbon and a maximum removal of 100 % was obtained at pH=3, 4 and 5 for an adsorbent dose of 1 g/L of 50 mg/L Chemactive D Black N concentration on activated carbon. The rate constants for adsorption were determined using Lagergren's equation. 2002, 51 pages Keywords: Textile dyes, adsorption, adsorption isoterms, adsorption kinetic, removal of colour 11
