Abstract
The adsorption of Lead (II) from aqueous solution by chitosan-g-maleic anhydride-g-methacrylic
acidcopolymer was investigated in fixed- bed column.The continuous adsorption varying the effect of flow rates, bed
height and concentration and breakthrough curves was evaluated and it was also analyzed by dynamics models
namely, Boharts and Adam, Thomas and Yoon and Nelson models at different conditions.The breakthrough data
fitted well to Thomas and Yoon Nelson models with high correlation coefficient, R

is 0.9835. The highest bed
capacity of chitosan-g-maleicanhydride-g-methacrylicacid adsorbent was obtained using 1 ml /min flow rate,
100 ppm inlet Pb metal ion concentration, and 3 cm bed height
