Abstract In this work we demonstrate the successful optimization of the interfacial polymerization reaction for the manufacture of organic solvent nanofiltration membranes by replacing the toxic amines commonly used for this method with the natural occurring bio-polyphenol morin. For the manufacture of this type of OSN membrane a crosslinked PAN support was coated by interfacial polymerization using morin as the monomer of the aqueous phase and terephthaloyl chloride as the monomer of the organic phase. These membranes showed an exceptional performance and resistance to NMP by having a permeance of 0.3 L/m2 h bar in NMP with a rejection of 96% of Brilliant Blue dye which has a molecular weight of 825.97 g/mol, making these membranes attractive for harsh industrial separation processes due to their ease of manufacture, low cost, and excellent performance.

用于有机溶剂分离过程的基于 Morin 的纳滤膜

摘要 在这项工作中，我们通过用天然存在的生物多酚桑椹取代通常用于该方法的有毒胺，证明了用于制造有机溶剂纳滤膜的界面聚合反应的成功优化。为了制造这种类型的 OSN 膜，交联的 PAN 载体通过界面聚合涂覆，使用 Morin 作为水相的单体，对苯二甲酰氯作为有机相的单体。这些膜在 NMP 中的渗透率为 0.3 L/m2 h bar，对分子量为 825.97 g/mol 的亮蓝染料的截留率为 96%，使这些膜对苛刻的环境具有吸引力工业分离过程由于其易于制造、成本低、
