The recovery of heavy metal, especially lead, in the used product is necessary for environmental protection. The recovery of lead is obligatory under the law, and consequently the manufacturing industries using lead as a materials are compelled to use the recycling lead, which contains a lot of impurity, in stead of the pure lead. In this project, the influence of impurity on conversion of the recycling lead to the oxide, PbO_2 was investigated. An electrochemical method made clear the effect of alloying element on the conversion behavior and the property of Pb-base alloy electrode, and the influence of impurity on the oxidation behavior near atmospheric temperature was revealed by the quartz crystal micro-balance technique (QCM technique). The results were published in three articles (See References), and the head investigator submitted a paper which concerned the influence of impurity on the oxidation behavior of lead thin film at room temperature. The information must be useful in the field of zinc electrowinning and lead-acid battery manufacturing.

回收废旧产品中的重金属，特别是铅，对环境保护是必要的。法律规定铅的回收是强制性的，因此以铅为原料的制造业不得不使用含有大量杂质的回收铅，而不是纯铅。本课题研究了杂质对回收铅转化为氧化物PbO_2的影响。电化学方法明确了合金元素对铅基合金电极转化行为和性能的影响，石英晶体微平衡技术（QCM）揭示了杂质对铅基合金电极近大气温度氧化行为的影响。结果发表在三篇文章中（见参考文献），首席研究员提交了一篇关于杂质对铅薄膜室温氧化行为影响的论文。这些信息对锌电积和铅酸电池制造领域有一定的参考价值。
