    Abstract: 本研究之主旨在於研發將奈米碳管(Carbon nanotube, CNT)披覆在較大尺度的玻璃載體上,並填充做為固相萃取管(Solid-phase extraction tube, SPE)用以吸附水相中的鄰苯二甲酸酯類(Phthalate esters, PAEs)。此固相萃取管除具備奈米碳管對苯環分子之優異吸附性質外,也同時具有高度熱穩定性以便高溫脫附之操作,以及高孔隙度利於水樣順利通過。因奈米碳管受限於其奈米尺寸,若直接以奈米碳管填充吸附管會有不透水性的問題,因此需將改質成尺度較大的奈米碳管複合材料。 本研究主要分為兩部分,第一部分是以化學鍵結法將奈米碳管披覆於載體表面,第二部分是比較商用吸附劑及CNT對PAEs做吸脫附的效能測試,化學鍵結法結果顯示以1-氮雜環丙烯氨化玻璃載體經化學鍵結法後,在玻璃載體表面擁有較多的奈米碳管較適合來製成奈米碳管複合材料,在對於PAEs的吸附效能測試實驗結果顯示,以多壁奈米碳管、Tenax TA與Carbotrap C填充之吸附管對於PAEs的吸附容量分別為50μg/g ~ 125μg/g、45μg/g ~ 121μg/g及38μg/g ~ 118μg/g,考慮通水後損失率及吸附效能,因此奈米碳管較Tenax TA及Carbotrap C適合用來吸附鄰苯二甲酸酯類。
    This study is intended to develop a solid-phase extraction tube based on carbon nanotubes (CNTs) embedded on glass particles. Carbon nanotube offers a new choice to traditional adsorbent material. CNTs has highly graphitic surface structure to suggest that the material is suitable for adsorption of organic compounds bearing aromatic rings. However, due to the nanometric size of CNTs, packed beds containery only CNTs is esscutially impermeable. Therefore, the embedment of CNTs on larger carriers becomes necessary to apply CNTs as a solid adsorbent.<br>This study mainly divides into two parts. The first part is series of surface chemical treatments is performed to make chemical bonding between multi-walled CNTs and glass beads (250μm). The second part is to compare adsorption volumn of phthalate esters by commercial adsorbents, CNTs and MWCNTs-embeded glass beads. The chemical bonding method result to demonstrate that using 1-aziridine to ammonification glass has more carbon nanotubes on glass beads after chemocal bonding. In PAEs adsorption volume by MWCNTs and commercial adsorbents result. The CNTs, Tenax TA and Carbotrap C adsorption volume separately as 50μg/g ~ 125μg/g, 45μg/g ~ 121μg/g and 38μg/g ~ 118μg/g. To consideration loss ratio after water flush and adsorption volume, therefore CNTs is suitable to use to adsorption the phthalate esters.
