近年来，用于去除废水中有机染料的高效吸附剂的开发引起了广泛关注。用聚合物对吸附剂进行表面改性是增强其吸附能力的一般策略。在这项工作中，首次开发了一种结合贻贝化学和 SET-LRP 的新策略，用于制造高效吸附剂，聚（对苯乙烯磺酸钠）改性的多壁碳纳米管（CNT）。还研究了这些基于 CNT 的聚合物纳米复合材料的吸附应用，用于从水溶液中去除阳离子染料（亚甲基蓝，MB）。一系列表征技术证实了这些基于碳纳米管的聚合物纳米复合材料的成功制备。此外，还研究了接触时间、MB浓度、吸附温度和时间等吸附参数的影响。根据实验数据，MB的吸附容量与接触时间成正比，与温度成反比。 MB对CNT-PDA-PSPSH的最大吸附容量为160 mg g−1，表明功能性CNT对MB具有优异的吸附性能。这项工作中描述的制备碳纳米管基聚合物纳米复合材料的方法简单、有效且通用，可以成为制备用于环境应用的高效吸附剂的通用策略。
The development of highly efficient adsorbents for the removal of organic dyes from wastewater has attracted much attention recently. Surface modification of adsorbents with polymers is a general strategy for enhancement of their adsorption capability. In this work, a novel strategy of a combination of mussel inspired chemistry and SET-LRP has been developed for the fabrication of highly efficient adsorbents, poly(sodium-p-styrene sulfonate) modified multi-walled carbon nanotubes (CNTs), for the first time. The adsorption applications of these CNT based polymer nanocomposites for the removal of a cationic dye (methylene blue, MB) from a water solution were also examined. The successful preparation of these CNT based polymer nanocomposites was confirmed by a series of characterization techniques. Furthermore, the influence of adsorption parameters including contact time, concentration of MB, adsorption temperature and time has been investigated. According to the experimental data, the adsorption capacity of MB was directly proportional to the contact time, while inversely proportional to the temperature. The maximum adsorption capacity of MB for CNT-PDA-PSPSH was 160 mg g−1, demonstrating the excellent adsorptive property of functional CNTs for MB. The method described in this work for the preparation of CNT based polymer nanocomposites is simple, effective and general, and could be a universal strategy for preparation of highly efficient adsorbents for environmental applications.
