电池用锌粉分析方法

Analysis method of zinc powders for alkaline Zn/MnO_2 batteries

无汞碱性锌锰电池用锌粉中有害杂质的含量极微,锌粉中加入了铝、铋、钙、铟、铅等金属缓蚀剂后,合金成分对某些原有的分析方法有干扰,杂质含量降低后,有的老方法灵敏度达不到,促进了新分析方法的研究和建立。对无汞碱性锌锰电池用锌粉的分析方法进行评述,以便读者更好地选择。

The contents of deleterious impurities in zinc powders for mercury free alkaline Zn/MnO2 batteries are very thimbleful.The components of alloys interfered the intrinsic analysis method because of the adding of some metals such as aluminum,bismuth,calcium,indium and lead which were used as inhibiter.The decrease of impurity contents results in bad sensitivity of the intrinsic analysis method and promotes the research and erect of new analysis methods.The author remarked the analysis methods of zinc powders for mercury free alkaline Zn MnO2 batteries,so that the readers could select a better method.
