摘要
利用实验室自制的壳聚糖交联不溶性腐殖酸小球为吸附剂,研究其对Pb(II)吸附动力学行为.结果表明:当Pb(II)初浓度分别为50、150和250 mg/L时,吸附均在5h达平衡.而且Pb(II)的初浓度为50和150mg/L时,吸附速率可按一级反应处理.
Batch experiments were carried out for the sorption of Pb(II)onto chitosan crosslinked insolublized humic acid beads.The operating studied was initial adsorbent concentration including 50,150 and 250mg/L.The sorption was analyzed using kinetic models and the sorption kinetics was found to follow a first-order kinetic model.
