When sourcing Ferrous Sulfate, understanding the distinction between its various hydrated forms is crucial for optimal application and procurement decisions. As a leading supplier, NINGBO INNO PHARMCHEM CO.,LTD. offers both Ferrous Sulfate Monohydrate (FeSO4·H2O) and Ferrous Sulfate Heptahydrate (FeSO4·7H2O). Each grade possesses unique properties that make it more suitable for specific applications in water treatment, agriculture, and industry. This guide aims to help B2B buyers and formulators make informed choices.

Ferrous Sulfate Heptahydrate, often referred to as green vitriol or copperas, is the most common form and typically appears as blue-green crystals. It contains approximately 19-20% elemental iron. Due to its higher water of hydration, it is generally less concentrated in iron compared to its monohydrate counterpart. This form is widely used in water treatment for coagulation and flocculation due to its effectiveness and availability. Many buyers seeking a standard, cost-effective iron source for large-scale water purification projects opt for the heptahydrate form.

Ferrous Sulfate Monohydrate, on the other hand, is a white to pale green powder and contains a higher concentration of iron, typically around 30%. This higher iron content makes it more efficient on a weight-for-weight basis for applications where iron concentration is a key factor. In agriculture, where precise nutrient delivery is important, the monohydrate form can be advantageous for correcting iron deficiencies in plants, as it provides more iron per unit mass. R&D scientists and formulators looking for concentrated iron sources for specialty products often prefer the monohydrate.

The choice between monohydrate and heptahydrate often depends on factors like application method, desired iron dosage, solubility needs, and cost-effectiveness. For instance, in agriculture, if soil amendments are bulky, the monohydrate might be preferred for easier handling and application. In water treatment, where large volumes are often treated, the lower iron concentration of heptahydrate might still be perfectly adequate and more economical. When you buy Ferrous Sulfate, understanding these differences ensures you get the most suitable product for your specific industrial or agricultural requirements.
