Food grade and medicine grade ferrous sulfate monohydrate powder in wet production Processes

Food grade high purity Specificaton

Preparation process:

There are various methods for preparing ferrous sulfate monohydrate, including the reaction of iron with dilute sulfuric acid and the reduction of iron sulfate by iron powder. In addition, the heptahydrate ferrous sulfate crystals can be mixed with a water-soluble organic dehydrating agent, stirred thoroughly in a sealed container, and the crystal water in the heptahydrate ferrous sulfate crystals can be dissolved and removed, and then dried to obtain the monohydrate ferrous sulfate powder product. Another method is to use ferrous sulfate heptahydrate, a by-product of titanium dioxide production by sulfuric acid method, as raw material, and prepare ferrous sulfate monohydrate through heating, adding reactants, standing, separation, filtration, and drying steps. There is also a wet production method that utilizes the solubility saturation state of ferrous sulfate aqueous solution, and then heats, evaporates, concentrates, and filters to obtain 12.

New application areas:

The traditional application fields of ferrous sulfate monohydrate include water treatment, printing and dyeing industry, pharmaceuticals, agriculture, etc. In recent years, its new application areas have been continuously expanding, such as:

In the metallurgical industry, ferrous sulfate monohydrate can be used as a reducing agent to extract metallic iron and other metallic elements; It can also be used as a desulfurizer to remove sulfur from ores and improve their quality.

In the chemical industry, ferrous sulfate monohydrate is an important raw material for synthesizing other compounds and can participate in various chemical reactions to prepare other chemicals with special functions, such as pigments, dyes, catalysts, etc.

In the feed industry, ferrous sulfate monohydrate can be used as a feed additive to provide iron nutrition for animals.

Storage method:

Ferrous sulfate monohydrate should be stored in a warehouse at low temperature, well ventilated, and dry, avoiding separate storage from food ingredients to prevent oxidation and deterioration. Meanwhile, due to the easy oxidation of ferrous sulfate monohydrate in air, it is usually necessary to seal and store it

By following these storage recommendations, you can ensure the safety, quality, and effectiveness of Ferrous Sulfate Monohydrate Powder for its various applications.
