超临界二氧化碳在环境保护中的应用

超临界CO2具有气体的低粘度、高扩散系数和液体的高密度特性，且具有化学惰性，无毒、无腐蚀性，临界状态容易实现，是一种性能优良的环境友好溶剂。文章概述了超临界CO2在去除环境污染物、取代传统工艺助剂或溶剂以减少有机物和废水排放以及分析测试等方面的应用。

Application of Supercritical Carbon Dioxide in Environmental Protection

Supercritical carbon dioxide is an environmentally friendly solvent due to its prominent properties,such as gas like lower viscosity and higher diffusion coefficient,liquid like higher density,chemical inertness,non toxicity,non corrosiveness and easily accessible critical point.The paper summarized some applications of supercritical carbon dioxide in environmental protection,such as removing environmental pollutants,replacing traditional process solvents to reduce wastewater discharge and waste organic gas emission,and the uses in analysis and detection,and so on.
