【摘要】 废旧干电池因含多种重金属及电解质而污染环境,将废旧干电池回收,并用于化学实验教学中,既减少了其对环境的危害,又符合绿色化学的要求。本文就干电池的构造进行了说明,同时设计了一系列利用废旧干电池中有效成分进行的综合性化学实验。更多还原

【Abstract】 Waste dry battery can pollute environment because of including many kinds of heavy metal and electrolytes.Recycling and applying them in chemistry teaching can not only reduce its harm to the environment,but also be fit for the demand of green chemistry.The article analyses the working mechanism,structure and main chemical compositions of waste dry batteries.At the same time some chemical experiments are designed according to how to make use of the effective compositions contained in the waste dry batteries.更多还原
