ABSTRACT This article describes the preparation of the polysulfone microcapsule (CPM) containing both 5,11,17,23-tetrakis[(dimethylamine)methyl]-25,26,27,28-tetrahydroxy calix[4]arene and magnetic nanoparticles. The structure of CPM was characterized using Fourier transform infrared spectroscopy, transmission electron microscopy, thermo gravimetric analysis and elemental analysis techniques. Moreover, heavy metal ions adsorption capability of the porous CPM toward Pb2+, Cu2+, Co2+, Cd2+ and Zn2+ ions was investigated. The results indicate that CPM exhibited selectivity in an order for Zn2+>Cu2+>Cd2+>Pb2+>Co2+. In addition, reusability studies for CPM were evaluated, and it was found that CPM could be reused without significant loss in their adsorption capacity for five times Zn2+ adsorption–regeneration cycles.

杯[4]芳烃固定化磁性微胶囊的制备、表征及其在重金属去除中的应用

摘要 本文介绍了含有 5,11,17,23-四[(二甲胺)甲基]-25,26,27,28-四羟基杯[4]芳烃和磁性纳米颗粒的聚砜微胶囊 (CPM) 的制备。使用傅里叶变换红外光谱、透射电子显微镜、热重分析和元素分析技术表征了CPM的结构。此外，研究了多孔 CPM 对 Pb2+、Cu2+、Co2+、Cd2+ 和 Zn2+ 离子的重金属离子吸附能力。结果表明，CPM 的选择性顺序为 Zn2+>Cu2+>Cd2+>Pb2+>Co2+。此外，对 CPM 的可重复使用性研究进行了评估，发现 CPM 可以重复使用而不会显着降低其吸附能力的 5 次 Zn2+ 吸附-再生循环。
