中文摘要:
      目前水环境中有机物污染问题日趋严重,在诸多水处理技术中,吸附法具有成本低、效率高、简单易操作等优点,研发高效吸附剂是决定高效能吸附处理过程的关键因素。环糊精因其价格低廉、无毒、环境友好等优势在水污染处理领域具有广阔的应用前景。环糊精具有外部亲水、内部疏水的圆台状独特结构,利用内腔可与极性分子形成主-客体包含物,因此,被用于水溶液中有机污染物的去除,其外部结构中存在大量羟基,表现出良好的亲水性和优异的化学反应特性,能够实现对溶液中有机污染物的高效去除,通过多种化学修饰或各种材料的有效复合,达到环糊精基复合吸附剂的高效功能化拓展。本文总结了多种环糊精基复合材料的制备方法,重点综述其对水体中有机污染物高效吸附去除的应用研究,探讨环糊精基复合材料的研究趋势和研究热点,对其未来研究方向进行展望。
英文摘要:
      At present, the problem of aquatic organic pollution is becoming more and more serious. Among many technologies for water treatment, adsorption technology has broad application prospect in water treatment thanks to its merits, including low-cost, non-toxic, and environment-friendly etc. The research and development of high efficiency adsorbent is the key factor to determine the process of high efficiency adsorption treatment. At the same time, the cyclodextrin has an externally hydrophilic, internally hydrophobic, frustum-like unique structure that utilizes the inner cavity to form a host-guest inclusion with polar molecules, so they are used as adsorbents for the efficient removal of the organic pollutants from aqueous solutions. Cyclodextrins show a great hydrophilicity and excellent characteristics of the chemical reaction, and can be used for the efficient removal of ions in the solution due to their external structures with many hydroxyl groups. Meanwhile, cyclodextrins implement a variety of chemical modification and complete the functional expansion of cyclodextrin adsorbent. Now, the modification of cyclodextrins become a hot issue. This paper reviewes the preparation of cyclodextrin-based composite adsorbents, and mainly summarizes the applied research of the effective removal of organic pollutants in water. The research trend and research hot spot of cyclodextrin-based materials are discussed in this review. Finally, the future research direction are expected.
