Adsorption properties of titanium(IV) hexacyanoferrate(II)

The possible use of titanium(IV) hexacyanoferrate(II) as a cation exchanger increased the interest in the preparation of materials with favourable ion exchange capacities and mechanical strength to be used in the columns. A new method of preparation has been developed, which is based on the treatment of spherical particles of titanium hydroxide gel with acidic solutions of potassium hexacyanoferrate(II). Materials of variable composition were obtained. The maximum value for the retention capacity for cesium was found to be of 2.6 meq. Cs per gram of ion exchanger.
