搅拌棒吸附萃取技术的研究进展

摘要

Stir bar sorptive extraction (SBSE) is a novel sample pretreatment method. Compared with solid phase microextraction, it has a larger solid phase volume and a higher extraction capacity. It can enrich analytes during self-stirring without an additional stirrer, which may cause competitive adsorption. So it has been widely used for pretreatment in food, environmental and biological samples. In this review, the recent research of stir bar sorptive extraction was summarized, including operating principle, novel coatings, novel extraction methods and the application of SBSE technique. The deficiency of SBSE was discussed and the development trend was also prospected.%搅拌棒吸附萃取是一种新型的固相微萃取样品前处理技术,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,广泛应用于食品、环境和生物样品分析的前处理.本文综述了搅拌棒吸附技术的最新应用进展,重点阐述了新型搅拌棒吸附萃取涂层的研制、新型萃取装置的发展以及搅拌棒吸附萃取技术的应用现状,并探讨了搅拌棒吸附萃取存在的不足,展望了搅拌棒吸附萃取技术的发展趋势.
