  • 本研究係以矽膠為基質, 加入適量矽烷耦合劑進行修飾反應, 再與三級胺
    反應, 以製備陰離子交換劑, 經由漿式填充後製備成陰離子交換管柱。以
    分離一些常見的陰離子, 並探討層析行為可能涉及的滯留機制。本論文選
    用3-氯丙基三甲氧基矽烷作為耦合劑, 與微粒細性矽膠(10μm)表面上
    的 -OH官能團進行反應, 製備含有機鏈的修飾矽膠, 再引入二乙基甲基
    胺, 即可製得具四級銨鹽之衍生物陰離子交換矽膠。本研究是以單管柱離
    子層析法配合電導偵檢計, 來探討試樣陰離子的層析行為。

    A silica-based anion exchanger for single-column ion
    chromatogr- aphy (SCIC) was prepared for by diethylmethylamine
    onto the sur- face of silane-modified silica-gel. The low
    capacities of anion exchanger were obtained and effective
    separation anions with a series of homologous dicarboxylic acid
    and cation with chelating agent(EDTA,Methyl-EDTA) as eluents
    usi- ng a conductormertic detector. Factors that can affect the
    retention behavior, such as eluent concentration, eluent pH,
    eluent species and capacities of anion exchanger were
    investigated.
