Release time: 2025-07-25

Q1: Does polyferric sulfate belong to the hazardous chemicals defined in the Catalogue of Hazardous Chemicals?

A1: It is not a legal hazardous chemical, but it needs to be handled carefully

According to the classification of the Catalogue of Hazardous Chemicals (2015 edition), polyferric sulfate is not listed as a hazardous chemical. Its logistics and transportation are usually treated as ordinary goods, and no relevant certificates for dangerous goods are required.

Q2: Why do some sources say it is dangerous?

A2: Due to strong acidity, corrosiveness and potential oxidation

Although it is not a legal hazardous chemical, polyferric sulfate has the following risks:

Strong corrosiveness: the liquid form is irritating to the skin, eyes and respiratory tract, contact can lead to burns, accidental ingestion may damage the digestive tract;

Oxidation: high concentration or mixed with other substances (such as alkali, alcohol) may cause oxidation reaction, there is a risk of fire or explosion;

Environmental impact: High concentration solution leakage may pollute water and harm aquatic life.

Q3: What safety measures should be taken when using polyferric sulfate?

A3: The operation must be standardized and equipped with protection

Personal protection: dust mask, rubber acid and alkali resistant clothes, goggles and gloves should be worn during operation;

Storage requirements: store in a cool, dry, well-ventilated environment, away from fire, combustible and incompatible substances (such as alkali, alcohol);

Leakage treatment: immediately rinse the contact with a large amount of water, and seek medical treatment.

Q4: Which scenarios require special attention to their risks?

A4: high temperature, high concentration and mixed reaction environment

The risk is significantly increased under the following conditions:

High temperature and high pressure environment may aggravate the oxidation reaction;

When mixed with reducing substances or organic matter, it is easy to react violently;

The production process requires a large amount of sulfuric acid, which requires professional equipment and technical personnel to operate.

Q5: What are the main uses of polyferric sulfate?

A5: high efficiency water treatment coagulant

As an inorganic polymer flocculant, it is widely used in:

Drinking water purification, industrial wastewater (such as printing and dyeing, electroplating, papermaking wastewater) treatment;

Decolorization, algae removal, heavy metal removal and COD/BOD pollutants, and no residual aluminum and chloride ions.

Conclusion

Ferric sulfate is not a legal hazardous chemical, but because of its strong corrosiveness and oxidation under specific conditions, it must strictly follow safety procedures. Users should assess the risks according to the actual application scenario, and operate according to product instructions and regulatory requirements.
