| 摘 要： | 采用吸附与解吸实验及盆栽试验，研究了在重金属镉、锌、铅复合污染条件下，棕壤对重金属的吸附、解吸规律，以及菠菜吸收重金属的特点。结果表明：棕壤对铅、锌的吸附分别符合Ｌａｎｇｍｕｉｒ、Ｆｒｅｕｎｄｌｉｃｈ方程，对镉的吸附用Ｌａｎｇｍｕｉｒ、Ｆｒｅｕｎｄｌｉｃｈ及Ｔｅｍｋｉｎ方程回归都不显。重金属被吸附后的解吸率顺序为：Ｚｎ〉Ｃｄ〉Ｐｂ。Ｐｂ＾２＋与吸附位结合的牢固程度较单一污染时大，而Ｃｄ＾２＋和Ｚ

| Abstract: | The pollution of cadmium, zinc and lead in brown earth were studied. the Langmuir and Freundlich isotherms were fitted the adsorption data for lead and zinc respectively. None of them is suitable to cadmium. The order of desorption ration of the metals was: Zn>Cd>Pb.The binding of lead to the adsorption site was enforced with the presence of other metals. The fractionation, as well as their availabilities to spinach, of the metals are different from each other. |
