Abstract

Finding eco-friendly solvents that can replace conventional toxic ones (N-methyl-2-pyrrolidone and dimethylacetamide) in the production of polymeric membranes is of great interest. In this study, membranes were produced using the phase inversion technique using polysulfone, polyvinylpyrrolidone, and Cyrene—a recently developed solvent, whose physicochemical profile is comparable to conventional ones, but is biodegradable, non-toxic, and eco-friendly. The resulting membranes were characterized regarding their morphological and structural properties, permeation performance, rejection of reference solutes and an emerging contaminant, and antifouling performance. Scanning electron microscopy, contact angle determination, Fourier transform infrared spectroscopy, and filtration tests were accomplished for that. It was possible to use Cyrene to produce polysulfone-based membranes, in which the one with 5% polyvinylpyrrolidone was the membrane with the highest permeability. Conversely, the membrane without polyvinylpyrrolidone and with a 30-min heat treatment achieved 73% rejection of the emerging contaminant evaluated.

使用绿色溶剂生产的聚砜基膜的性能评估

在生产聚合膜的过程中，寻找可以替代传统有毒溶剂（N-甲基-2-吡咯烷酮和二甲基乙酰胺）的环保溶剂是非常有意义的。在这项研究中，我们使用聚砜、聚乙烯吡咯烷酮和最近开发的溶剂 Cyrene（一种理化性质与传统溶剂相似，但可生物降解、无毒且环保的溶剂），通过相反转技术生产出了膜。所制备的膜在形态和结构特性、渗透性能、对参考溶质和一种新出现的污染物的排斥以及防污性能等方面都具有特点。为此进行了扫描电子显微镜、接触角测定、傅立叶变换红外光谱和过滤测试。使用 Cyrene 生产聚砜基膜成为可能，其中含 5%聚乙烯吡咯烷酮的膜渗透性最高。相反，不含聚乙烯吡咯烷酮并经过 30 分钟热处理的膜对所评估的新污染物的阻隔率为 73%。
