The adsorption behavior of crystal violet (CV(+)) from aqueous solution onto raw (RB) and acid activated (AAB) bentonite samples was investigated as a function of parameters such as initial CV(+) concentration, contact time and temperature. The Langmuir and Freundlich adsorption models were applied to describe the equilibrium isotherms. The adsorption rate was fast and more than half of the adsorbed-CV(+) was removed in the first 55 min for RB and 25 min for 0.2-AAB at the room temperature (C(0… CONTINUE READING
