Ferrous SulfateCAS:7720-78-7Product Introduction:Ferrous sulfate
heptahydrate commonly known as alum, is a blue-green crystal
or particles, mainly used for iron fertilizer, pesticides,
pigments, medicine, etc., in addition to chromatographic analysis
reagents. It is a by-product of the sulfuric acid process in the
production of a rare metal product. The product is a light green or
yellowish-green crystalline solid. ItemSpecificationTest

Features:The color of ferrous sulfate heptahydrate is green,
monoclinic crystal or particle, no odor, relative density 1.898,
melting point 64ºC. Easily soluble in water, (48.6g/100ml water at
50ºC) red heat decomposition to form ferric trioxide, soluble in
glycerol, insoluble in ethanol, corrosive, in dry air will be
weathered. At 56.6ºC, the heptahydrate is transformed into
tetrachlates, and at 64.6ºC, it becomes monohydrate. At 90ºC, six
crystalline water is lost, and at 300ºC, all crystalline water is
lost to form anhydrous substance. At red heat, SO2 and SO3 are
decomposed and released. It's corrosive. It fluoresces in dry air.
The anhydrous substance is a white powder, but when it is mixed
with water it turns blue-green.Usage:1.As a reducing agent: ferrous
sulfate is a strong reducing agent, can be the water content of the
electroplating plant chromium wastewater hexavalent chromium
reduction into trivalent chromium.2.As a flocculant: ferrous
sulfate is widely used as a flocculant, it has the following
advantages as a flocculant: Sedimentation speed, large granular
sludge, the sludge volume small and compact, except for the color
effect is good, very suitable for as a textile wastewater, printing
and dyeing, washing processing), non-toxic and beneficial organisms
(very suitable for use in the subsequent biochemical treatment
process of wastewater treatment system), without changing the
original technology, and the price is low, as a flocculant, Ferrous
sulfate can replace polymeric aluminum, basic aluminum chloride,
polymeric iron, aluminum sulfate and so on. Dyeing, electroplating
and other wastewater treatment worthy of the product.3.As a
precipitator: ferrous sulfate and sulfide, phosphate and other
precipitation, so as to remove sulfide, phosphate, etc., for
example, with ferrous sulfate treatment of printing and dyeing
plant sulfur wastewater.Packing&Shipping:Packing: 25kg/bag
or ton bag neutral packing or
customized.Shipping: 25-27MT will be loaded in per 20'FCL container.Store: The
product shall be sealed and stored in the dry and ventilated place
