ABSTRACT

The ability of cow dung ash without any pretreatment to remove color from textile dyes N Blue RGB, Green B and EOSINYWS from aqueous solution has been investigated in this work. Cow dung ash, an ecofriendly and low cost adsorbent wasprepared by burning cow dung cakes in the mufle furnace at 500˚C. The adsorption was achieved under diferent pH andadsorbate concentration. The data was fitted to simple polynomial and the isotherms similar to Langmuir and Freundlichisotherms.
