This study developed a beta-cyclodextrin polymer crosslinked with citric acid (CDCAPol) for removing water contaminants using methylene blue (MB) as a model compound. The polymer, which features free carboxyl groups and cyclodextrin cavities, demonstrated high adsorptive capacity. Under optimal conditions (0.01 g adsorbent, pH 6, and 50 mg/dm MB), a removal efficiency of 99.2% was achieved, with a maximum adsorption capacity of 126.58 mg/g as determined by the Langmuir isotherm. Kinetic data fit the best to the pseudo-second-order model, highlighting strong interactions between MB and the polymer. This promising material may find applications in wastewater treatment and environmental protection.
本研究开发了一种用柠檬酸交联的β-环糊精聚合物（CDCAPol），以亚甲基蓝（MB）为模型化合物去除水中污染物。该聚合物具有游离羧基和环糊精空腔，表现出高吸附容量。在最佳条件下（0.01 g吸附剂、pH值为6和50 mg/dm的MB），去除效率达到99.2%，根据朗缪尔等温线测定的最大吸附容量为126.58 mg/g。动力学数据最符合准二级模型，突出了MB与聚合物之间的强相互作用。这种有前景的材料可能在废水处理和环境保护中得到应用。
