Abstract Membrane technologies are a sustainable solution for treatment of water and wastewater. Here, the technical feasibility of polystyrene-halloysite nanotube (PS-HNT) membranes, fabricated by an ultrasound-assisted solution casting method, was explored for water purification. To this end, the effects of various solvents on the structure, morphology, thermal, and mechanical properties of PS-HNT membranes were investigated. Introduction of HNTs (5 wt%) into the polystyrene matrix demonstrated excellent thermal and mechanical properties along with good water flux, rejection of unwanted components, recovery, and regeneration cycles. These membranes were overall useful enough to purify real wastewater collected from pulp and paper mill.

用于水净化的聚苯乙烯-埃洛石纳米管膜

摘要 膜技术是处理水和废水的可持续解决方案。在这里，探讨了通过超声辅助溶液浇铸方法制造的聚苯乙烯-埃洛石纳米管 (PS-HNT) 膜用于水净化的技术可行性。为此，研究了各种溶剂对 PS-HNT 膜的结构、形态、热和机械性能的影响。将 HNT (5 wt%) 引入聚苯乙烯基体表现出优异的热性能和机械性能以及良好的水通量、去除不需要的成分、回收和再生循环。这些膜总体上足以净化从纸浆和造纸厂收集的真实废水。
