碩士 === 國立高雄師範大學 === 化學系 === 101 === A Fe3O4@Nia-C11-COOH magnetic particle was synthesized and used for the first time as an effective adsorbent for the enrichment of the alkylphenols(4-n-nonylphenol, and 4-n-octylphenol) prior to high- performance liquid chromatography detector. An analytical method using Fe3O4@Nia-C11-COOH magnetic solid-phase extraction (MSPE) and HPLC analysis for the simultaneous determination of alkylphenols has been developed. In this work, iron oxide particles have been prepared successfully by a reversed-micelle method of Fe(II) is modified Nia-C11-COOH. The characters of the synthesis steps were investigated. The research major analysis the extraction efficiencies were investigated by HPLC for Fe3O4@Nia-C11-Br-COOH. The optimal conditions and the extraction efficiencies are reported.
