氧氮杂大环配体液膜传输铜的动力学研究

On Transport Kinnetics of Transport of Copper(Ⅱ) Cations Across Liquid Memberane by Both OXA and AZA macro Heterocyces

利用超分子化学研究了大环配体液膜对金属离子选择性识别和传输．主要研究了１２－十八烷基－１，４，７，１０－四氮杂环十三烷－１１，１３－二酮大环配体的氯仿－辛醇液膜在大量镍（Ⅱ）存在下对铜的传输动力学及选择性．结果表明，传输是通过中性配合物进行的，无阴离子参与，选择性良好。

A study was made on the liquid membrane transport kinetics of copper(Ⅱ) in the presence of nickel(Ⅱ)in chloroform/octanol solution of 12 octdecyl 1,4,7,10 tetraazacyclotridecanne 11,13 dione (ODTD) as the ion carrier. The results shaw that transport of copper(Ⅱ) was surported by neutral complexes and indepentent of anions and was not affected by nickel(Ⅱ) cation when present.
