环境分析技术的研究进展

The development of environmental analysis technologies

环境问题是当前全球关注的重大问题，而环境分析技术则是环境监测综合技术核心，近年来得到越来越多科研工作者的广泛重视。本文介绍固相微萃取技术、膜分离技术、超临界流体萃取（SFE）的原理、应用范围及其应用前景。最後封中国环境分析技术的发展方向提出了自己的建议。

The environment problem is great concerned in the world, and environmental analysis technologies are the core technologies in the environmental monitoring. In recent years more and more workers pay more and more attention on these technologies. In this paper, the principle, scope and application of Solid-Phase micro-extraction technology, membrane separation technology, and SFE are introduced. At last, some suggestions on the research and development orientation of environmental analysis technologies in China are presented.
