Product Description
Ferrous sulfate, chemically denoted as FeSO4, commonly appears in a hydrated form-FeSO4·7H2O-widely recognized as green vitriol. It presents as light-blue-green monoclinic crystals. In dry air, this compound undergoes efflorescence, while in humid conditions, it readily oxidizes, forming a brown-yellow layer of basic ferric sulfate on its surface. Highly water-soluble, ferrous sulfate yields a light-green aqueous solution with weak acidity.
Chemically formulated as FeSO4, ferrous sulfate commonly exists in a hydrated state as FeSO4·7H2O, widely referred to as green vitriol. It exhibits as light-blue-green monoclinic crystals. In dry air, this compound experiences efflorescence, whereas in a humid environment, it is highly prone to oxidation. Consequently, a brown-yellow coating of basic ferric sulfate develops on its surface. Ferrous sulfate dissolves readily in water, producing a light-green aqueous solution with a slightly acidic nature.

Application
Pigments and Colorants
Application: Serves as a raw material for preparing iron-based pigments (such as iron oxide green and iron blue), or directly used for coloring concrete and gypsum products.
Characteristics: Ferrous sulfate heptahydrate particles exhibit a light green color. Upon drying and dehydration, the color deepens, allowing for tone adjustment by controlling moisture content.
Application Scenarios: Building materials (colored floor tiles, coatings), artistic pigments, and leather dyeing.Application Scenarios: Municipal sewage treatment plants, industrial wastewater pretreatment, and reclaimed water reuse systems.
Industrial - grade ferrous sulfate is of great significance in water treatment. Once it is dissolved in water, hydrolysis occurs to produce a ferrous hydroxide colloid, which has remarkable adsorption capabilities. Take the treatment of natural water or industrial wastewater with sediment and suspended particles as an example. The ferrous hydroxide colloid can adsorb the suspended impurities in the water, causing them to aggregate and settle. In this way, the goal of purifying the water quality is attained. Water Treatment Coagulant
Usage: As an inorganic flocculant, it is used to remove suspended solids, heavy metal ions, and organic matter from water.Mechanism of Action: Fe² is oxidized to Fe³ in water, forming ferric hydroxide colloid, which adsorbs impurities and promotes precipitation.When used in combination with lime, polyaluminum, etc., it can enhance the effect of sewage treatment (such as printing and dyeing wastewater, electroplating wastewater).
In the printing and dyeing industry, ferrous sulfate is employed as a mordant. It has the ability to form a combination with dye molecules, facilitating the better adhesion of dyes to fabric fibers. This action enhances the dyeing effect, ensuring that the dyeing is more stable and even. For instance, during the dyeing process of cotton fabrics, pre-soaking the cotton fabrics in a ferrous sulfate solution before proceeding with the actual dyeing step can effectively increase the dye absorption rate and the color fastness of the fabrics.
Applications: Used in analytical chemistry (e.g., as a reference substance for determining iron content via method) and coordination chemistry experiments (for preparing iron complexes).
Storage Precautions: Ferrous sulfate heptahydrate particles are prone to oxidation in air. Store them in a sealed container in a cool, dry place to prevent deliquescence and color change (from light green to brownish yellow).
Catalysts and Experimental Models
Application: As a core component of Fenton's reagent, applied in scientific research experiments for the degradation of organic pollutants.
Packaging & Shipping
Packing: Package in 25/50/1000kg bag, also accpet customer OEM packing.
Storage: Keep in a cool, dry, dark location in a tightly sealed container or cylinder.
