分离技术的进展

本文概述了基于生物技术的发展、超纯材料的制备等对发展分离科学和技术的需求,特别是从大量基体物或稀溶液中提取、分离、纯化和检测低含量物质要求发展高选择性的分离技术和相应的分离体系。在发展和完善原有分离技术(如萃取、离子交换、吸附、吸收等)的同时,超临界萃取和膜分离技术具有引入的应用前景。还应注意两种或多种分离技术相结合的分离方法和技术的研究。

Progress of Separation Technology

The needs and development of separation science and technology are reviewed, In view of developing the biotechnology and material science, especially preparating superpure materials, protecting and improving the environment. developing alternative energy sources and resources for chemicals, high selective separation technologies and the related separation systems are needed for extraction, separation, purification and determination of low species content from the matries or dilute solations.At the some time for developing and improving the well known separation technologies, i. e.. solvent extraction, ion exchange, adsorption, sbsorption etc., the new technologies of supercritical extraction and membrane separation are very attractive and prospective.In addition, it should be noted that the combined separation methods by two or multiple kinds of separation technology may be more valuable.
