An apparatus for in situ observation of adsorbed species at alloy electrode/solution interfaces was developed in the present research. It permitted observation of drug adsorption on dental alloy electrodes. The obtained results are as follows.1. An apparatus for in situ observation of adsorbed species at alloy electrode The apparatus consists of equipments for voltammetry, specular reflection, in situ electrochemical quartz crystal microbalance (EQCM) etc. Eltctrochemical properties of various dental alloy electrodes in artificial saliva were obtained by voltammetry. Usefulness of the specular reflection and EQCM for studying adsorption of iodide ion on gold electrode was assessed.2. Adsorption and surface reaction of druge at alloy of precious metals Interactions between dental alloys of precious metals and oral germicidal drugs were examined using the apparatus. A very thin films, one or two monolayr, of AgI and CuI were formed on the alloy surfaces in artificial saliva containing compound iodine glycerin.3. Interaction between alloy of base metals and compound iodine glycerin. No surface layr was observed on dental alloy of base metal in arificial salive containing compound iodine glycerin. Elution of metal ions from Ni-Cr alloy was caused by iodine in compound iodine glycerin.The apparatus was shown useful for in situ observation of trace substances at alloy electrode/solution interfaces.

研制了一种原位观测合金电极/溶液界面吸附态的装置。它允许观察牙科合金电极上的药物吸附。主要研究结果如下：1.本装置由伏安法、镜面反射法、现场电化学石英晶体微天平（EQCM）等仪器组成，用伏安法测定了不同牙科合金电极在人工唾液中的电化学性质。评价了镜面反射法和EQCM法用于研究碘离子在金电极上吸附的可行性.药物在贵金属合金上的吸附和表面反应用该装置研究了牙科贵金属合金与口腔杀菌药物的相互作用。在含复合碘甘油的人工唾液中，AgI和CuI在合金表面形成一层或两层很薄的单层膜.复合碘甘油与贱金属合金的相互作用。含复方碘甘油的润滑剂在牙科基合金表面未观察到表面层。本文介绍了在复合碘甘油中碘对Ni-Cr合金中金属离子的溶出作用，该装置可用于合金电极/溶液界面上痕量物质的现场观察。
