由于人口增长加快、气候变化以及自然和人为污染的增加，提供安全可靠的饮用水的挑战正在加剧。目前的水处理厂不能有效地去除普遍的、亲水的、低分子量的污染物，这些污染物会对人类健康产生不利影响。在此，我们描述了一种绿色全水合成的离子交换树脂，该树脂由共价结合到单壁碳纳米管的短链双刷组成。将该复合材料结合到膜上，并针对分析物吸附测试活性位点。我们对水或盐水通过这些材料的控制研究发现，没有证据表明单壁碳纳米管（SWCNT）或碳/聚合物从膜过滤器中出来。我们测量了十种不同化合物（药物、农药、消毒副产品和全氟烷基化物质）的吸附能力和去除百分比。我们已经测量了它们的去除效率高达95- 100%。聚电解质和随后的纳米树脂的合成、纯化、动力学和表征如下所示。材料作为薄膜进行测试。再生能力被测量到20个循环，材料已被证明是安全和可重复使用的，使它们成为可持续水净化的潜在候选者。
The challenge of providing safe and reliable drinking water is being exacerbated by accelerating population growth, climate change, and the increase of natural and anthropogenic contamination. Current water treatment plants are not effective at the removal of pervasive, hydrophilic, low molecular weight contaminants, which can adversely affect human health. Herein, we describe a green all-aqueous synthesis of an ion exchange resin comprised of short chain polyelectrolyte brushes covalently bound to single walled carbon nanotubes. This composite material is incorporated onto a membrane and the active sites are tested against analyte adsorption. Our control studies of water or brine pushed through these materials, found no evidence of single-walled carbon nanotubes (SWCNTs) or carbon/polymer coming out of the membrane filter. We have measured the adsorption capacity and percentage removal of ten different compounds (pharmaceuticals, pesticides, disinfection byproducts and perfluoroalkylated substances). We have measured their removal with an efficiency up to 95–100%. The synthesis, purification, kinetics, and characterization of the polyelectrolytes, and the subsequent nanoresin are presented below. The materials were tested as thin films. Regeneration capacity was measured up to 20 cycles and the material has been shown to be safe and reusable, enabling them as potential candidates for sustainable water purification.
