摘要：Textile effluents are the one most calumnious threat to the environment, which have a lot of chroniceffect towards the human beings. Color 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 naturallyavailable materials. Tunic of Allium cepa (TAC) had been chosen as an Adsorbent, as it is abundantly available.Powdered TAC (PTAC) was used for optimization studies for the removal of selected dyes from the textileeffluents. The selected dyes are safranine, Indigoid, Alizarin Red S and Crystal violet belongs to the Azo andAnthraquinone family dyes respectively. These dyes are selected as they are not degradable easily and are very toxicin nature. The optimum percentage removal of selected dyes from the textile effluent was 70, 53, 40 and 68respectively.
