超临界流体在环境保护中的应用和展望

Application and Future of Supercritical Fluid in Environmental Protection

超临界流体技术广泛应用于化工、医药、生物、食品、陶瓷等领域。将超临界流体技术用于环境保护则是一个新的研究方向,由于该技术对废物处理具有经济、快速、高效等特点,近几年来发展异常迅速。综述了超临界流体的特性以及超临界流体技术(超临界萃取、超临界色谱和超临界水氧化)在环境保护方面的应用现状。

Supercritical fluid technology is extensively applied in the fields of chemical engineering, medicine, biology, food, poreelain etc. It is a new rese arch aspect to apply the supercrltical fluid technology on environmental protection. The technology has gotten extremely rapid development for recent years because of its many advantages such as low-price, good-speed and high-efficiency in disposing of wastes. The specialties of supercritical fluid and the application status quo of supercritical fluid technology （supercritical fluid extraction, supercritical fluid chromatography and supercritical water oxidation） in environmental protection were summarized in this paper.
