研制了一种具有硝基苯（NB）/水（W）界面的新型微流池。使用聚（聚乙烯）膜过滤器来制备NB/W界面，其形成在薄通道（0.1mm厚，48 cm.长）在银盘上。预先电解银板，并用作Ag/AgCl电极，用于控制NB/W界面上的伽伐尼电位差以及检测流过界面的电流。使用微流池，完成了代表性离子（即，四甲基铵离子）。因此，本发明的微流池显示出对于库仑（即，绝对定量）离子分析。此外，微流池被证明是有用的，用于确定在油/水界面的复杂的电荷转移过程的电子数。
A novel microflow cell with a nitrobenzene (NB)/water (W) interface was developed. A poly(tetrafluoroethylene) membrane filter was employed to prepare the NB/W interface which was formed over a thin channel (0.1 mm thick, 48 cm. long) on a silver plate. The silver plate was electrolyzed in advance and served as an Ag/AgCl electrode for controlling the Galvani potential difference across the NB/W interface as well as detecting the current flowing through the interface. Using the microflow cell, complete electrolysis was accomplished for the interfacial transfer of a representative ion (i.e., tetramethylammonium ion). Thus, the present microflow cell was shown to be promising for coulometric (i.e., absolute quantitative) analysis of ions. Also, the microflow cell was shown to be useful for determination of the number of electrons for complicated charge-transfer processes at the oil/water interface.
