Abstract

In this study, the adsorption characteristics of Naphthol Green from aqueous solution onto activated carbon prepared from Natural clay like Bentonite was investigated under various parameters like the adsorption capacity, initial dye concentration, contact time, effect of solution pH and adsorbent dosage were investigated in a batch mode. The adsorption isotherms data have been tested by applying both Frendlich and Langmuir isotherm models. The separation factor R value was found to be between 0 and 1 for the adsorbent, it indicate that the feasibility of adsorption. The result showed that this activated bentonite had a high adsorption capacity (Qo = 253.14 mg/g). The kinetics data fitted to the pseudo-first- order model. The results indicate that natural clay like activated bentonite could be employed the removal of textile dyes from industrial effluents.
