Lohtragon® V01 | Type 703

Q: What are Iron Sulfates?

Iron Sulfates are inorganic salts of sulphuric acid and iron. Ferrous Sulfates contain Fe²⁺ cations and are pale green, while Ferric Sulfates contain Fe³⁺ cations and are yellow-brown. They are soluble in water and widely used in industrial, environmental, and agricultural processes.

Q: What are Iron Sulfates used for and why?

Surface treatment & etching: applied for controlled metal etching and surface preparation. Water purification: used to bind and precipitate heavy metals, improving water quality. Chemical synthesis: serve as catalysts or reducing agents in various processes. Electronics: enable precise copper etching for circuit production. Coatings & pigments: provide stable iron sources for color and surface properties.

Q: Where are our Iron Sulfates produced?

They are produced at our manufacturing facilities in Germany.

Q: What is special about our Iron Sulfates?

Over 135 years of expertise in mineral and specialty salts Exclusive production in Germany with strict process control High-purity materials with consistent iron content Full batch traceability and transparent supply chain Compliance with EU REACH and food-contact regulations where applicable

Q: What is the difference between Ferrous and Ferric Sulfates?

Ferrous Sulfates (Fe²⁺): pale green, provide reactive iron for reduction processes. Ferric Sulfates (Fe³⁺): yellow-brown, offer stable iron for oxidation, pigmentation, and surface treatment applications.

Q: What is the difference between liquid and solid Iron Sulfates?

Solid forms such as powders or granules are easier to transport, store, and flexibly dissolve to required concentrations. Solutions are ready-to-use, allow precise dosing, reduce dust exposure, and can be more practical in continuous or large-scale operations.
