硫酸钴(七水)制备

1.金属钴法：将金属钴板溶于硫酸及硝酸的混合酸中，用蒸汽加热至沸，反应后经浓缩、结晶、分离母液，制得硫酸钴。

氧化钴用硫酸溶解氧化钴，溶液经蒸发浓缩、结晶、离心脱水，制得硫酸钴。

2.将200mL浓硫酸加入到1300mL水中，并加热到90～98℃，然后慢慢地分次加入300g Co2O3。当激烈反应阶段结束后，分次加入27mL浓度为37%的甲醛溶液(每次1～2mL)。此时溶液变得完全透明，过滤除去机械杂质。将滤液蒸发浓缩至出现晶膜，冷却到5～10℃，抽滤，将结晶在35～45℃下干燥。可以获得500～600g CoSO4·7H2O产品。

3.将含量约为22%的硫酸溶液，加热至90～98℃，然后缓慢加入三氧化二钴：

待反应平缓后，分次加少量甲醛，以还原剩余的三氧化二钴：

反应结束后，将溶液过滤（滤去机械杂质），滤液蒸发浓缩至结晶薄膜出现，冷却至5～10℃，粉碎析出的结晶，抽干，在35～45℃干燥至松散，即得分析纯品。母液回收利用。

4.将1份工业品硫酸铜溶于3.5份水中，滤去杂质，滤液蒸发浓缩至结晶薄膜形成，搅拌下用水冷却结晶，抽干，在空气中干燥即可。母液回收利用。
