硫酸铁制备

1.用氧化物或氢氧化铁跟硫酸反应制得将三氧化二铁溶于含量为75%～80%的沸腾硫酸中得到硫酸铁。或者用硝酸氧化黄铁矿。
2.将七水合硫酸亚铁溶于水中。加热，向其中分次加入硫酸以及硝酸，加热至95～100℃。直至Fe2+已全部转化为Fe3+为止。过滤溶液，加入硫酸，蒸发至形成黏稠状，此时温度约为120℃，冷却至40～50℃，吸滤出结晶，于65℃干燥，得纯品硫酸铁。 3.将无水硫酸亚铁与浓硫酸共煮，即可生成无水硫酸铁，反应完全后，用玻璃砂芯漏斗将硫酸铁过滤出来，用无水乙醇和乙醚洗涤后真空干燥即可。也可将水合硫酸铁慢慢加热，让其逐步脱水，最后完全脱水成为无水盐。 4. 用水溶解硫酸亚铁，加热至70℃，慢慢地分次加入理论量的密度为1.84的硫酸，再加入密度为1.35的过量硝酸，控制温度为95～100℃，进行氧化反应：当氧化反应完全后，停止加热，过滤后，往滤液中加入少量硫酸，进行蒸发，浓缩至粘稠状，温度达120℃，冷却至40～50℃，滤出结晶，在不超过65℃下干燥即可。
