- Bentonite clay from Maghnia (North West Algeria) has been acid-activated. The activated bentonite was employed as adsorbent for the removal of methyl green from aqueous solutions using adsorption method. The influence of several parameters (kinetics, contact time, sorbent amount, adsorbate concentration and pH) on the adsorption capacity was evaluated and discussed. The Langmuir adsorption model was applied to experimental equilibrium data and the isotherm constant was calculated. The results indicated that the adsorption was favourable at neutral pH. This model provided the best fit to the experimental data with high correlation coefficient (R²=0.996). The monolayer adsorption capacity of activated bentonite found to be 353.33 mg/g. It was seen that pseudo-first order equation describes the adsorption kinetics. The results indicated that this bentonite-type clay is potential to be used as an economical adsorbent for the removal of methyl green dye.
