%X A composite adsorbent chitosan-grafted-poly(acrylic acid)/sepiolite was prepared,and its pH-dependence for removing Pb~(2+),as well as adsorption isotherm and kinetics were estimated.The results indicate that poly(acrylic acid) has been grafted onto the backbone of chitosan,forming an organic-inorganic composite adsorbent.As-prepared adsorbent shows a coarse,porous and accidented surface,which can contribute to its adsorption kinetics.Under the conditions of pH 6.00,contact time of 30 min,initial Pb~(2+) co...
