Product Description
Ferrous Sulfate Monohydrate (FeSO₄·H₂O, Molecular Weight: 169.92, CAS No.: 13463-43-9, EINECS: 231-753-5) is a high-purity industrial inorganic iron salt processed by drying and dehydrating heptahydrate ferrous sulfate under controlled temperature conditions. It appears as an off-white to beige crystalline powder, dissolves rapidly in water, and is completely insoluble in ethanol. Compared with heptahydrate ferrous sulfate, this product features lower moisture content, higher effective iron concentration, and minimal caking risk during long-distance transportation and warm storage.

Application
-
Agricultural & Turf Management:
Corrects iron deficiency and chlorosis in crops, stimulates chlorophyll synthesis, lowers alkaline soil pH, and effectively eradicates moss and lichen on lawns and orchard trees without deliquescence risks in fertilizer blending. -
Industrial Manufacturing & Wastewater Treatment:
Serves as a prime raw material for iron oxide pigments, iron red, inks, and iron salts; functions as a mordant in dyeing, a wood preservative, and an efficient reducing agent for precipitating heavy metals and phosphate pollutants in sewage treatment.
