| 中文摘要: |
| 搅拌棒吸附萃取（Stir Bar Sorptive Extraction，SBSE）是20世纪90年代末发展起来的一种新型无溶剂样品前处理技术，具有固定相体积大、萃取容量高、无需外加搅拌子、可避免竞争性吸附、能在自身搅拌的同时实现萃取富集等优点，已广泛应用于环境、食品和生物等复杂样品中目标物质的痕量分析。涂层是SBSE技术的核心，决定了萃取选择性和容量。本文简要介绍了SBSE涂层的萃取原理、萃取解吸模式及其影响因素，重点阐述了近年SBSE涂层制备技术与方法，探讨了SBSE涂层发展中的不足，并展望了其发展趋势。 |
| 英文摘要: |
| Introduced in 1999 as a solventless sample preparation method, Stir bar sorptive extraction (SBSE) has been widely appied to the trace enrichment of various target analytes in environmental, food and biological samples, due to its large volume of the stationary phase, high pre-concentration capacity, no additional stirring, avoiding competitive adsorption, allowing sample extraction and preconcentration to be done in a single step at the same time of self-stirring and so on. Coating is the core of SBSE technique, which determines the selectivity and extraction capacity of analysis. In this review, a brief introduction of extraction principle, extraction/desorption mode and their influencing factors of the stir bar sorptive coatings are made, and then the preparation techniques and methods of SBSE coatings are focused on. Finally, the advantages and disadvantages of SBSE coatings are discussed and overview of future development trends of SBSE coatins is given. |
