超临界流体色谱在纺织检测中的应用
|
摘要
随着对纺织品可能带来的环境与生物危害性的日益关注,建立快速响应、高灵敏度的测试分析方法成为纺织产业新的诉求。超临界流体色谱以超临界流体和少量助溶剂为流动相,基于不同化合物在两相间的各异分配系数进行物质分离,其兼具气相色谱和液相色谱的优点,并具有黏度低、传质性好和绿色环保的优势,在低挥发性物质的分析分离上发挥了重要作用。从系统构成、流动相、固定相方面对超临界流体色谱进行了系统介绍。同时,综述了超临界流体色谱在纺织品中致敏染料、聚合物添加剂、荧光增白剂等检测中的应用。
With the growing concern of the international community on the possible environmental and biological hazards from textiles,the establishment of novel rapid response and high sensitivity test method is becoming the new demand for textile industry. In supercriticalfluid chromatography, separation of substances is carried out based on the different partition coefficients of different compounds in thetwo-phase when supercritical fluid and a small amount of co-solvent are employed as the mobile phase. Furthermore, supercritical fluidchromatography displays the advantages of gas chromatography and liquid chromatography, and also presents the characteristics of lowviscosity, excellent mass transfer, as well as green and environmental protection, which plays a vital important role in the analysis andseparation of low volatile substances. The supercritical fluid chromatography is introduced systematically from the aspects of systemcomposition, mobile phase and stationary phase. Moreover, the application of supercritical fluid chromatography in the textile detection,including sensitizing dyes, polymer additives and fluorescent whiting agents in textiles is reviewed.
