RATZIR® is an inorganic sorbent based on zirconium hydroxide. RATZIR-K, a composite version, contains microparticles of zirconium hydroxide, chemically fixed on granules of natural aluminosilicate. The porous support in the sorbent composition provides greater access to sorption sites which increases the capacity of the sorbing agent and improves the kinetics of sorption.
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.
