Product Usage

Ferric Sulfate is an important inorganic iron salt with the chemical formula Fe₂(SO₄)₃, appearing as pale yellow powder or crystals, soluble in water and with good chemical stability. Its core application is in the water treatment field as an efficient flocculant, which can quickly adsorb suspended particles, organic matter and heavy metal ions in water. It is widely used in drinking water purification, industrial wastewater treatment and sludge dewatering, with better purification effect than traditional flocculants and no secondary pollution. In the agricultural field, it can be used as an iron fertilizer to supplement iron elements in soil, prevent iron deficiency chlorosis of crops, and improve crop yield and quality. In addition, it is used in printed circuit board etching, pigment manufacturing, pharmaceutical intermediate synthesis, as well as leather tanning, water treatment agent compounding and other fields, with high efficiency and economy, and is an indispensable chemical raw material in industrial production.
