摘要:甲壳素经化学改性制得的壳聚糖吸附Cu^(2+)、Ni^(2+)、Zn^(2+)、Ca^(2+)、Rb^+、Cs^+、Cd^(2+)、Pb^(2+)等离子的研究已有报道,但吸附Pd^(2+)等贵金属离子的研究尚不多见.本文报道了壳聚糖及其交联产物的造粒方法,并测定了该糖吸附Hg^(2+)、Cu^(2+)、Ag^+、Pd^(2+)等离子的特性.结果表明,化学交联后的颗粒(作吸附剂)在酸性条件下仍保持相当好的刚性,对Pd^(2+)离子的吸附容量较大,在Pd^(2+)、Cu^(2+)共存时可选择性吸附Pd^(2+).
Chitosan and the particles of its crosslinked derivatives were manufactured,and the adsorption properties for Hg2+ ,Cu2+ , Ag+ and Pd2+ were studied in this paper. The result indicates that the particles keep its rigidity in the acidic solution,the capacity for Pd2+ is 480 mg/g, and it has an adsorption selectivity to Pd2+ when Cu2+ and Pd2+ are present simultaneously in the solution. These particles could be used in collecting precious metals from waste water.
