Description

DescriptionIron(II) sulfate heptahydrate, also known as this compound, is a blue-green crystalline solid with the chemical formula FeSO₄·7H₂O. It is commonly referred to as green vitriol or copperas. This compound is widely used in various industries, including agriculture, water treatment, and pharmaceuticals, due to its versatile properties.Application1.Water treatmentFerrous sulfate is used for flocculating and purifying water, and removing phosphate from urban and industrial sewage to prevent eutrophication of water bodies.2.Reducing agentA large amount of ferrous sulfate is used as reducing agent, which mainly reduces chromate in cement.3. ColorantThe production of a tannic acid inks and other inks requires ferrous sulfate. Ferrous dye is also used in wood dyed mordant.SpecificationsItemFerrous Sulphate HeptahydrateFeSO4 7H2OFerrous Sulphate MonohydrateFeSO4 H2OPurity %min9891AppearanceGreen crystal or granularGreywhite powderFe % min19.730Pb ppm max2020As ppm max22Cd ppm max55Type of Packaging25 Kg woven bag1000Kg jumbo bagsCertificationsISO 9001.
