摘要
考察了交联聚乙烯亚胺螯合树脂对溶液中铜离子的吸附性能,开展了饱和吸附容量、等温吸附曲线、PH 影响曲线以及吸附速度测定等实验。结果表明,此交联螯合树脂对溶液中铜离子具有吸附能力强、吸附速度快等特点,可望用于含铜废水的处理及回收。
A PAN based cross-linking resin has been used as absorbent for copper(Ⅱ).The factors which affect the absorption capacity of the absorbent and the absorption mechanism are discussed in detail.The experimental results show that the absorbent has high absorption capacity which can reach 0.96mmol copper(Ⅱ) calculated by every gram of resin,and the absorption velocity is fast.
