| 摘 要： | 研究了无汞碱性电池各主要组成部件（由内至外为：锌粉、浆纸、碳粉、金属外壳、塑料包皮）内汞（Hg）、砷（As）的分布规律和随时间变化规律。将不同出厂时间的电池按上述部件解剖消解后,分别采用原子荧光光谱法（AFS）测定各部件中Hg、As含量,进而分别绘制出其随环境存放时间变化图。结果表明：电池中Hg总量随在环境中的存放时间延长而下降,As总量则增加。电池中不同部位Hg、As含量差别较大;且随着存放时间延长,各部件含量变化明显。而电池表面选材对汞、砷的分布及迁移影响显著。

| Abstract: | The distribution and time-varying migration of mercury,arsenic were studied in various major components(zinc,plasm paper,toner,metal shell and plastic package from the inside to the outside)of the mercury-free alkaline batteries.The contents of mercury,arsenic in major components of batteries with different production time were determined respectively by atomic fluorescence spectrometry(AFS) after digestion.Then the charts for the contents of mercury,arsenic variational with storage time were drawn.The tota... |
