Basic Fuchsin (BF) is a toxic triphenylmethane dye with molecular formula C20H20ClN3, which is easy to caused serious public health problems. There is a need to develop a cost effective method for its removal from the wastewater containing BF. Here, a novel composite polymer adsorbent, poly (maleic anhydride - acrylic acid - vinyl acetate)/Na-bentonite composite cross-linked with N,N'-methylenebisacrylamide was prepared by in situ copolymerization. The polymer adsorbent (NaB-PMAVM) was characterized and applied to remove BF. It was found that the removal of BF reached to 95.96%. The adsorption isotherms and kinetics were best-fit with the Freundlich isotherm model and the pseudo-second-order kinetic, respectively.
