A two-dimensional metal deposit can be obtained by the cathodic reduction of the metal at the interface between an organic liquid and an aqueous solution. One advantage of this technique is that any solid substrate is not needed. Therefore, as one of attractive application of this technique, electrochemical conditions were surveyed for preparing purified metallic films in this study.Firstly, experimental techniques were developed to maintain uniform growth of metallic films along the interface, ; The given distance between the counter electrode and the growth front of the metal was held, by moving the counter electrode.Secondly, effects of impurities in aqueous solutions were examined on the growth and purity of zinc electrodeposited. The additions of Cu and Fe ions influenced scarcely on the growth of zinc,but the addition of Pb ions resulted in an uniform growth of zinc. Pb and Cu enriched in zinc, but Fe did not enrich.Fundamental information to obtain purified metallic films by this technique was obtained.Above results will be very useful for preparing highly purified metallic films.

通过在有机液体和水溶液之间的界面上对金属进行阴极还原，可以获得二维金属沉积。这项技术的一个优点是不需要任何固体衬底。因此，作为该技术的一个有吸引力的应用，本研究综述了制备纯净金属膜的电化学条件。首先，开发了实验技术以保持金属膜沿界面的均匀生长；通过移动对电极来保持对电极与金属生长前沿之间的给定距离。其次，考察了水溶液中的杂质对电沉积锌的生长和纯度的影响。铜、铁离子的加入对锌的生长影响不大，而铅离子的加入使锌的生长均匀。铅、铜富锌，铁不富集，为制备高纯金属膜提供了基础信息。
