摘要/Abstract

摘要： 研究了脱乙酰壳多糖吸附重金属离子的最大吸附量与平衡时间。研究表明,用和不用氮处理所得到的脱乙酰壳多糖对重金属离子的吸附能力无明显差异。脱乙酰壳多糖对铅、铬、铜及镉离子的结合是非特异性的。

Abstract: Chitosan has the property of binding heavy metal ions.Its maximum amount of adsorption and equilibrium time have been studied.There is no significant difference in the adsorp-tion ability between chitosan treated with nitrogen and those without nitrogen treatment. Chitosan shows nonspecific adsorption in the binding heavy metal ions such as plumbum, chromium,Copper,Cadminm.

Key words: chitosan, heavy metal ions, waste water treatment
