硫酸钴(七水)制备

【方法一】
金属钴溶解于硫酸和硝酸（约4：1）的混合酸中。质量分数达22%-23%时，用蒸汽直接加热至沸
当质量分数达43%-44%时，即可进行结晶(3-4)天，经离心分离得成品。母液质量分数越30%,加入35%-36%的硫酸溶液，再加入少量的硝酸，用以溶解金属钴。
反应中产生的NO3（NO很快被空气NO2）可用氨水吸收，副产硝酸铵。
【方法二】
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。其
3Co+2HNO3+3H2SO4→3CoSO4+2NO2↑+4H2O
2NO+O2→2NO2↑
氧化钴法用硫酸溶解氧化钴，溶液经蒸发浓缩、结晶、离心脱水，制得硫酸钴。其
CoO+H2SO4→CoSO4+H2O
