摘　　要：为了从废旧锌锰电池中制得更高等级的四水氯化锰,对四水氯化锰制备过程中的除铁方法,如水解法、加氨水法、焙烧法等进行了实验研究。结果表明:采用290±10℃焙烧法除铁不仅工艺简单、操作方便,而且能够使产品中铁的含量达到分析纯化学试剂标准。In order to make higher grad manganese chloride tetrahydrate from waste zinc-manganese batteries,the experiments on iron removal in making manganese chloride tetrahydrate are done with the methods as hydrolysis ammonia treatment, calcinations and so on.The results shown that the best method of the iron removal is calcination, the suitable calcining temperature is 290±10℃.In this condition, the content of the iron in the product can reach to the standard of analytically pure manganese chloride tetrahydrate.
