纳滤分离原理及其在中药制药中的应用
【摘要】:膜分离技术作为一种新型的分离纯化技术，已经在化工等领域得到应用，而在中药行业的应用较少。本文介绍了纳滤的基本概念、特性和分离机制，包括常见的模型：溶解－扩散模型、细孔模型、Donnan平衡模型、电荷模型等。以及这些模型的适用范围和在实际中药制药过程中应用的新进展，并对纳滤技术的应用和发展前景做了展望。

【Abstract】As a new type of separation and purification technology, membrane separation technology has been applied in many fields like chemical engineering. But it applied less in the field of traditional Chinese medicine pharmacy. This paper introduces the basic concepts and characteristics of nanofiltration, researching NF process mechanism, including some common models like: Dissolution-Diffusion effect，Steric Pore effect, Donnan effect,Electric Charge effect and so on. And new research progress on the application of membrane separation technology was presented in the traditional Chinese medicine pharmacy and the research prospects of membrane separation technology were also been pointed out.
【Key words】Process mechanism; Nanofiltration; Traditional Chinese Medicine
