A Study on Synthesis of Zeolite and Removal of Amido Black dye by adsorption with Zeolite

Abstract

Investigations have been undertaken to determine whether cheap, commercially available materials (natural zeolite and bentonite) hold promise in the treatment of wastewaters from the textile industry. The initial findings indicate that zeolite synthesized from fly ash has high adsorptive capacity for dyes and it is relatively cheap. The adsorption of two basic dyes (Amido Black and Thionine) onto granular activated carbon as well as zeolite from fly ash and bentonite has to be studied as single equilibrium isotherms. The effectiveness of each adsorbent has to be measured in terms of its adsorption capacity towards individual constituents of the effluent. The adsorption isotherm would be described by the Langmuir and Freundlich isotherm equations. The parameters in the adsorption isotherms will be estimated from the experimental equilibrium data using non-linear regression analysis. Using these data, the selection of the best adsorbent can be done for design purposes.
