摘要
研究了利用硫化亚铁做还原剂处理废旧干电池制取硫酸锰(MnSO4)的实验原理、工艺流程及实验条件。实验结果表明:硫酸浓度和还原剂的用量对反应影响很大。获得了以硫化亚铁为还原剂制取硫酸锰的最佳反应条件:当硫酸用量为15mL,反应温度70℃,硫化亚铁用量为0.8g和反应时间3h时,硫酸锰的产率可达80%以上。
Experimental principle,technological process and conditions were studied on producing manganese sulfate with ferrous sulfide as reductant for treating waste Zn/Mn dry battery.The results showed that sulfuric acid concentration and amount of ferrous sulfide affect the reaction remarkably.It was concluded that the optimal reaction conditions for producing manganese sulfate were：sulfuric acid of 15 mL,the ferrous sulfide of 0.8 g,reaction time of 3 hours at 70 ℃ and the recovery rate of manganese sulfate over 80%.
