Removal of Textile Effluent dyes using Tunic of Allium Cepa

Abstract

Textile effluents are the one most calumnious threat to the environment, which have a lot of chronic effect towards the human beings. Colour is the main experimental variable to recognize the water has contaminated. Out of many techniques, Adsorption is attaining a specific place of importance due to its scope choosing naturally available materials. Activated Carbon from Tunic of Allium cepa (ACTAC) had been chosen as an Adsorbent, as it is abundantly available. ACTAC was used for optimization studies for the removal of selected dyes from the Textile effluents. The selected dyes are safranine, Indigoid, Alizarin Red S and Crystal violet belongs to the Azo and Anthraquinone family dyes respectively. These dyes are selected as they are not degradable easily and are very toxic in nature. The optimum percentage removal of selected dyes from the textile effluent was reported as 80, 70.95, 45 and 74 respectively.
