硒酸亚铁

硒酸亚铁是一种无机化合物，为二价铁的硒酸盐，化学式为FeSeO4。其五水合物的结构为[Fe(H2O)4]SeO4·H2OK. Heinzinger, G. Pálinkás, Hubertus Kleeberg.

制备
硒酸亚铁可以通过饱和的硒酸钠和硫酸亚铁溶液在80℃混合，冷却至20℃后沉淀出来，用丙酮洗涤后于120℃干燥。Filonenko, E. N.; Vergeichik, E. N.. Preparation and analysis of cobalt (II) selenate and iron (II) selenate. Farmatsiya (Moscow), 1998. 47 (3): 36-37
 Na2SeO4(sat.) + FeSO4 → Na2SO4 + FeSeO4 
铁和硒酸的反应也能得到硒酸亚铁，但是也有副反应：A E H Tutton. Selenic Acid and Iron. - Reduction of Selenic Acid by Nascent Hydrogen and Hydrogen Sulphide. - Preparation of Ferrous Selenate and Double Selenates of Iron Group . Proceedings of the Royal Society A, 1918 , 94 (241) :352-361
 Fe + H2SeO4 → FeSeO4 + H2↑
 3 Fe + 4 H2SeO4 → 3 FeSeO4 + Fe + 4 H2O
相关物种
硒酸亚铁还可以形成矾，如(NH4)2Fe(SeO4)2·6H2O。三价铁的硒酸盐Fe2(SeO4)3也是已知的。G Giester, F Pertlik. Synthesis and crystal structure of iron(III) selenate(IV) trihydrate, Fe2(SeO3)3·3H2O. Journal of Alloys & Compounds, 1994 , 210 (1-2) :125-128

亚铁的亚硒酸盐尚未有文献报道，对应的三价铁亚硒酸盐和焦亚硒酸盐已被制得。Pinaev, G. F.; Stukan, R. A.; Makarov, E. F.. Moessbauer effect in iron(3+) selenites. Zhurnal Neorganicheskoi Khimii, 1977. 22 (7): 1731-1733
