摘要： In this study, the adsorption effect of Pb2+ and Cd2+ was investigated using amphoteric modified bagasse hemicellulose as adsorbent. The heavy metal ions adsorbed increased slowly after 30 min, and remained stable after 180 min. Application of level-2 dynamic model describing the amphoteric modified bagasse hemicelluloses gave the adsorption capacity of lead and cadmium were at 65.79 mg.g(-1) and 36.23 mg.g(-1), respectively. At the temperature of 293 K, the pseudosecond-order dynamics equations for the adsorption of Pb2+ and Cd2+ were as follows: dq(t)/dt = 0.0231(65.79 - q(t))(2), dq(t)/dt = 0.0428(36.23 - q(t))(2). Ion coexisting experiments showed that the affinity of Pb2+ was much higher than that of Cd2+.
