研究了以聚丙烯中空纤维为模板，制备具有三维多孔结构的二氧化钛和氧化锆中空纤维的简便方法。建立了水样中N，N-二甲基乙酰胺(DMA)的中空纤维吸附微萃取-气相色谱快速分析方法。结果表明，氧化锆中空纤维比二氧化钛中空纤维具有更高的DMA萃取性能。考察了方法的线性、检出限、检出限、精密度和重复性。六点校正曲线线性良好，氧化锆中空纤维r(2)值大于0.9993，线性范围为0.001~10 mg mL(-1)。此外，中空纤维吸附萃取法是一种无需任何其他前处理而直接从液体样品中提取的分析物的浓缩和纯化技术。(C)2009爱思唯尔B.V.保留所有权利。
The convenient fabrications of titania and zirconia hollow fiber with three-dimensional porous structure using polypropylene hollow fibers as templates were developed. And an analytical method based on enrichment and extraction of analytes in the water sample, hollow fiber sorptive microextraction in combined with gas chromatography has been developed for the rapid analysis of N,N-dimethylacetamide (DMA) in the environmental samples. The results showed that zirconia hollow fiber gave higher extraction performance of DMA than that of titania hollow fiber. The method validations, including linearity, limit of detection, limit of qualification, precision, and repeatability were investigated. Linearity for six-point calibration curve was excellent with zirconia hollow fiber having r(2) value greater than 0.9993 at the linearity range of 0.001-10 mg mL(-1). In addition, it seems that hollow fiber sorptive extraction is a promising technique for the enrichment and purification of analytes extracted directly from liquid samples without any other pretreatment.
