Ferrous sulfate, known chemically as iron(II) sulfate, is a versatile chemical compound that comes in various forms and grades, each suited for specific applications. Understanding these differences is crucial for businesses looking to source the right product for their needs, whether in agriculture, water treatment, or other industrial processes. When you buy ferrous sulfate, knowing the grade ensures optimal performance and cost-efficiency.

The most common forms encountered are ferrous sulfate heptahydrate (FeSO₄·7H₂O) and ferrous sulfate monohydrate (FeSO₄·H₂O). Ferrous sulfate heptahydrate, often appearing as blue-green crystals, is widely used in agriculture for soil conditioning and correcting iron chlorosis, as well as in water treatment for coagulation and phosphorus removal. It's also a common form for pharmaceutical applications, particularly for iron supplements to combat anemia.

Ferrous sulfate monohydrate, typically appearing as whitish or pale green crystals, has a higher iron content per unit weight and generally offers better stability. This higher iron concentration can lead to reduced transportation and handling costs per pound of iron, making it an attractive option for large-scale industrial applications or when a more concentrated iron source is needed. Its use in animal feed as a supplement to prevent anemia is also notable.

When selecting a manufacturer or supplier, it's important to consider the intended application. For most water treatment and agricultural needs, ferrous sulfate heptahydrate is a standard choice. For animal feed or applications where higher iron concentration and stability are prioritized, monohydrate might be preferred. NINGBO INNO PHARMCHEM CO.,LTD., as a leading supplier in China, offers various grades to meet these diverse requirements.
