摘　　要：从氢氧化亚铁制备的化学原理入手,分析了Fe-H2O体系的电势-pH图和氧气对实验制备的干扰及溶液密度对制备效果的影响。在控制反应体系的pH值和反应溶液的密度及隔离空气的条件下,研究得出了实验室制备氢氧化亚铁的最佳可行方案。For the preparation of ferrous hydroxide, the Fe-H20 system＇s electric potential-pH graph, the interference caused by oxygen and the relation between solution density and production rate were analysed based on chemical theory. The optimized conditions were obtained after experimentally adjusing the pH value and the density of solution of the reaction system. Also, it was found that the system should be isolated from air.
