摘要
以回收的废干电池为原料,使其在硫酸溶液里酸解。在所得的溶液中加入过量分析纯过硫酸铵(20%)除去溶液里的铁、锰等杂质,然后以碳酸钠为沉淀剂,采用直接沉淀法制备出前驱体,经无水乙醇溶液洗涤数次,在95℃的烘箱中干燥完毕后,在600℃的马弗炉中焙烧2h,制备出超细氧化锌粉体,粉体的平均粒度为5.12μm,并对此氧化锌进行抗菌性能的初步分析。
The outworn dry cells were used as the materials. They were put into vitriolic solution. Adding the analytic pure excess 20 percent amount（NH4）2S2O8 into the reaction solution in order to doff Fe, Mn and some impurities. Na2CO3 was used as sediment agent to produce zinc hydroxide by equable sediment method. After cleaning by ethanol several times and drying at 95℃ ,superfine powder of zinc oxide could be obtained baking at 600℃ for two hours. Average granularity is 5.12μm. Some basic analysis were studdied on the granularity and antibacterial quality of the superfine powder.
