  • Dehydration of iron(II) sulfate heptahydrate -

    2007-10-15 · Thermal dehydration of iron (II) sulfate heptahydrate has been studied by a number of investigators. Diev [22] considered that the true structure of heptahydrate is (FeSO 4 ·H 2 O)·6H 2 O. Heptahydrate can be easily dehydrated to the monohydrate in 5–7 min and to FeSO 4 in 120 min by heating isothermally at 200 °C.
