摘要
利用化学共沉淀法,在处理铬渣的同时,制备四氧化三铁。通过等离子体发射光谱仪检测,分析出四氧化三铁的纯度和产率,并讨论了铁盐浓度、沉淀剂浓度以及温度对产率和纯度的影响。
Fe3O4 was prepared by using chemical precipitation in dealing with chromium residue simultaneously.Detected by plasma emission spectrometer,the purity and yield of Fe3O4 were analyzed,and concentration between iron and nutrient,precipitant concentration and temperature on the yield and purity was discussed in this paper.
