硫酸高铁铵,十二水制备

1.将400份70～80℃的热纯水加入200份工业品硫酸亚铁中，搅拌溶解，减压过滤。滤液中加40份工业硫酸和10份28%～30%的工业品双氧水，进行氧化反应：

当褐色溶液变为浅红棕色时，用铁氰化钾检验亚铁完全氧化（无蓝色沉淀）。将已氧化合格的溶液加热到70～80℃，赶掉剩余双氧水，蒸发至饱和慢慢加入32份工业硫酸铵和80份纯水配成的硫酸铵热溶液：

搅拌下使之冷却至0℃ （不允许超过10℃），析出的晶体甩干后常温下干燥，得粗品。粗品用50℃的热水搅拌溶解，使密度为1.28～1.30，维持温度为45～55℃，加入少量双氧水，充分搅拌0.5h，使Fe²⁺离子完全氧化成Fe³⁺，过滤后让清液充分静置结晶，结晶过程中经常搅拌，以便得到小颗粒晶
体，晶体甩干，搅动下常温晾干。母液可蒸发再结晶。
