| 摘 要： | 研究了一种新型的重金属离子吸附体系－含磺酸基的PET离聚物（SPET）对重金属离子Cr(III)及Cu(II)吸附性能，研究发现，随吸附时间的升高，吸附量会明显增加，4h后达到平衡，平衡吸附量随溶液浓度的增大而提高，离聚物SPET中碳酸钠基因含量越大，其吸附平衡值也越大。

| Abstract: | The adsorption properties of a new kind of adsorbent, Sulphonated poly(ethylene terephalate) ionomer (SPET) towards Cr(III) and Cu(II) in aqueous solution were studied in this paper. It was found that the adsorption increases as the time evolution and achieves equilibrium value after 4 hr. The higher equilibrium adsorption value can be obtained under the conditions of higher solution concentration and ion contents of SPET. |
