Organic solvents take up 80% of the total chemicals used in pharmaceutical and related industries, while their reuse rate is less than 50%. Traditional solvent treatment methods such as distillation and evaporation have many disadvantages such as high cost, environmental unfriendliness, and difficulty in recovering heat-sensitive, high-value molecules. Organic solvent nanofiltration (OSN) has been a prevalent research topic for the separation and purification of organic solvent systems since the beginning of this century with the benefits of no-phase change, high operational flexibility, low cost, as well as environmental friendliness. Especially, hollow fiber (HF) OSN membranes have gained a lot of attention due to their high packing density and easy scale-up as compared with flat-sheet OSN membranes. This paper critically reviewed the recent research progress in the preparation of HF OSN membranes with high performance, including different materials, preparation methods, and modification treatments. This paper also predicts the future direction of HF OSN membrane development.
有机溶剂占制药及相关行业所用化学品总量的80%，而其再利用率不到50%。传统的溶剂处理方法，如蒸馏和蒸发，有许多缺点，如成本高、不环保，以及难以回收热敏性、高价值分子。自本世纪初以来，有机溶剂纳滤（OSN）一直是用于有机溶剂体系分离和纯化的热门研究课题，具有无相变、操作灵活性高、成本低以及环保等优点。特别是，与平板式有机溶剂纳滤膜相比，中空纤维（HF）有机溶剂纳滤膜因其高填充密度和易于放大生产而备受关注。本文批判性地综述了高性能中空纤维有机溶剂纳滤膜制备方面的最新研究进展，包括不同的材料制备方法和改性处理。本文还预测了中空纤维有机溶剂纳滤膜的未来发展方向。
