摘要
对于许多化工产品废物,如塑料、有毒物质、生物污泥和有机废水等,利用传统技术进行处理的效果较差。超临界流体(SCF)技术作为一种清洁环境的新技术,可用于治理化工污染物。SCF作为反应介质或反应物可替代有毒、有害有机溶剂;用作萃取剂,它是一种新型的分离技术;以SCF作移动相的色谱,可提高检测灵敏度和分辨率;将超临界水作为氧化剂,可破坏有机污染物的结构。SCF技术的应用可以大大减少环境污染。
Many chemical waste products such as plastic matter, toxicants, biological sludge and organic sewage are hard to be treated with the traditional treatment method. Supercritical fluid (SCF) is a new technique for clean environment and removal of chemical pollution. It can replace the harmless organic solvent, when supercritical fluids are taken as reactant or reaction medium. Supercritical fluid extraction is a new separation technique. The supercritical fluid can be taken as extracting solvent to separate the extractants. The supercritical fluid chromatography taken supercritical fluid as migration phase can be used to analyze the organic pollutant and enhance the detection sensitivity and resolution. The supercritical water oxidation can destruct the structure of organic pollutants. The application of supercritical fluids technique can greatly reduce the environmental pollution.
