RATZIR® based on zirconium hydroxide  extractd ions of polyvalent metals, including lead and bismuth, ions of silicon, iron, manganese and antimony from aqueous solutions. It is used for removal of radon decay products and alpha-emitting radionuclides.

ABOUT PRODUCT

Sorbent RATZIR® is inorganic sorbent based on zirconium hydroxide. Sorbent is available in two versions: RATZIR and RATZIR-K (composite).

RATZIR-K contains microparticles of zirconium hydroxide, chemically fixed on granules of natural aluminosilicate (opal).

The porous support in the sorbent composition provides greater access to sorption sites which increases the capacity of sorbing agent and improves the kinetics of sorption. Chemical formula of absorbent material is ZrOх(OH)у, where x = 0 – 1, y = 2 – 4.

Zirconium hydroxide may extract ions of polyvalent metals, including lead and bismuth, ions of silicon, iron, manganese and antimony from aqueous solutions. It is used for removal of radon decay products and alpha-emitting radionuclides.
