Abstract

Study on the removal of Acid Green 20 by adsorption on indigenously prepared activated carbons from cow dung, mango stone, parthenium leaves and commercial activated carbon have been carried out with an aim to obtain information on treating effluents from tanneries. The effects of various experimental parameters have been investigated by following the batch adsorption technique. Adsorption data was modeled with the Freundlich and Langmuir isotherms. Removal of Acid Green 20 was found to be favorable using Biomass ash and could be considered as alternatives to commercial activated carbon for the treatment of tannery effluents, especially for the removal of dye(s).
