Iron(II) sulphate monohydrate neutralised is mainly used in the cement industry for reduction of hexavalent chromium.

Enrichment of cement with dry ferrous sulphate reduces the content of chromium, which is known to cause stinging and allergies. The EU directive requires that all cement manufacturers reduce the chromium compounds. Furthermore, it can be used as an additive to fertilizers to enhance the iron content, control of plant chlorosis or an addition of peat.

The Integrated Management System in POLICE Chemical Company S.A. includes the Quality Management System ISO 9001:2000 (confirmed with the TÜV NORD POLSKA certificate has been functioning in POLICE Chemical Company S.A. since 23 January 2004), the Environmental Management System ISO 14001:2004 and the Occupational Health and Safety Management System PN-N 18001:2004 (compliant with the International Standard OHSAS 18001). In case of iron (II) sulphate, due to the possibility of its application as addition for feed, the Hazard Analysis and Critical Control Points system (HACCP) and the Food Safety Management System according to EN ISO 22000:2005 have been implemented.

Packing, storage and transportation

FESPOL® 14 should be transported in a covered transport in accordance with the applicable transport regulations. Products should be stored in clean and dry storage buildings or on the squares with protection from rain. Product should also be protected from moisture and kept away from heat sources.

KNOWLEDGE BASE

Iron(II) sulphate as an intermediate manufactured during the production of TiO2

Generally, titanium dioxide is white, but has a slightly yellowish color due to the absorption of the visible light portion of the particles corresponding to the blue color.

Iron sulphate – respected intermediate product used in the chemical industry

For many years, ferrous sulfate is used for production coagulants and wastewater treatment. It is also used for the production of iron pigments. In the cement industry is used as the reducing agent of hexavalent [...]
