碩士 === 國立高雄師範大學 === 化學系 === 104 === An analytical method using Fe3O4@ppy magnetic particles as a magnetic-solid- phase extraction adsorbent, simultaneously determined three chlorophenols of 2,4-dichlorophenol (2,4-DCP), 2,3,4,6- chlorophenol (2,3,4,6-TeCP), pentachlorophenol (PCP) by HPLC . In this study, the magnetite (Fe3O4) were prepared by the chemical co-precipitation method of Fe(Ⅲ)/ Fe(Ⅱ), and modified with Fe(Ⅲ), pyrrole, SDS by common ion effect, further the Fe3O4@ppy was synthesized. Extraction efficiencies by Fe3O4@ppy of chlorophenols compounds was determined. The results showed that the limit of detection for three chlorophenols (2,4-DCP, 2,3,4,6-TeCP, PCP) were 0.49 ng/mL, 0.67 ng/mL, 0.93 ng/mL. The range of good linearity was 0.002 to 0.2 μg/mL. The enrichment factors were 32 to 55. When the method applied for real sample, three chlorophenols did not detect in Houjing river. The recovery ranges were from 95 to 105%. It is a easy, simple and efficiency method to analyze the chlorophenols.
