摘　　要：本文研究了硫酸亚铁溶液氧化制备硫酸高铁溶液过程的影响因素。研究发现,一定条件下,硫酸亚铁-硫酸体系中,温度、氧分压及反应时间的增加可以提高二价铁的转化率;反应温度为110℃,釜表压2 bar,反应时间为4 h,可以获得90%的二价铁转化率。This article introduced the study of preparation process of ferric sulfate solution from ferrous sulfate via oxygen oxidization method. Results show that the enhancement of temperature, partial pressure of oxygen and retention time increases the ferrous conversion rate into bar of gage pressure as well as 4 h retention time, ferric ion. Optimum is determined as 110 ℃ of temperature, 2 under which ferrous ion conversion reaches 90%.
