摘    要:纳米纤维极具优越固相萃取介质的潜质,基于纳米纤维的固相萃取法( Nanofibers based solid phase extraction, NFs-SPE)已成为新兴的样品预处理技术。本文在评述NFs-SPE在食品、环境样品、生物样品等实际样品检测应用的相关研究基础上,提出纳米纤维的分子结构和形态结构与目标物吸附效能之间存在着“结构”-“效应”关系,这将是明确纳米纤维高效吸附目标物的机理的关键突破口。

关 键 词:纳米纤维  固相萃取  吸附效能  分子结构  形态结构  综述

Solid Phase Extraction Technique Based on Electrospun Nanofibrous
Abstract:Nanofibers have been considered as a potential kind of sorbent for solid phase extraction, accordingly nanofiber-based solid phase extraction ( Nanofibers based solid phase extraction, NFs-SPE ) becomes a popular research point of sample pretreatment technique. This article reviewed in and abroad research status of practical application in food, environmental and biological sample preparation based on nanofibers mat, and proposed that there was a dual “structure”-“activity” relationship between target adsorption efficiency and the two structures ( nanometer morphological structure and molecular structure ) of nanofibers, which would be the key breakthrough to explore adsorption mechanism.
Keywords:Nanofibers  Solid phase extraction  Adsorption efficiency  Molecular structure  Morphological structure  Review
