【摘要】 <正>自1967年Pedersen首次合成冠醚化合物到现在的近二十年中,冠醚在分析化学中的应用已受到了广泛的重视,尤其是在溶剂萃取、离子选择性电极和液相色谱等领域中。 冠醚不仅能和许多阳离子、阴离子和中性分子形成络合物,而且可通过控制冠醚中心孔穴的大小和立体结构来达到对这些离子或分子的多种选择性,这种可凋性是冠醚的更多还原

【Abstract】 This paper is a review with 57 references. The crown compounds can be applied in the field of analytical chemistry, such as solvent extraction, ion-selective electrode, and liquid chromatography. In this paper we mainly discuss the application of crown ethers inorganic liquid chromatography, Called crown ether phase inorganic liquid chromatography ( CEPILC ) , where they may be used as the mobile or the stationary phase and have excellent ion selectivities. Compared with the conventional ion-exchange chromatography, CEPILC do not need corrosion-proof pump and column because pure water or water/mcthanol mixtures can be utilized as the eluent instead of aqueous solutions of acid or alkali.更多还原
