| 中文摘要: |
| 纳滤是介于反渗透和超滤之间的一种膜分离技术。综述了纳滤膜的特性，分离机理(其分离机理数学模型包括空间电荷模型、固定电荷模型、静电阻碍模型和道南一细孔模型)及其在水处理、制药业、食品及染料等行业过程中的应用，并对其更广泛的发展前景进行展望。 |
| 英文摘要: |
| Nanofiltration is a pressure-driven membrane-separation technique similar to reverse osmosis filtration and ultrafiltration. In this paper, the mechanisms of nanofiltration are discussed in brief and relevant mathematical models, such as the space charge model, the fixed charge model, the e1ectrostatic and steric-hindrance mode1, and Donnan-steric pore model, are described. Applications of nanofiltration membranes in water treatment, pharmaceutical industry, food and dye industries etc. are reviewed. In addition, future prospects on the development of nanofiltration are presented. |
