Adsorption properties of titanium(IV) hexacyanoferrate(II)

Adsorption of 137Cs on titanium ferrocyanide and transformation of the sorbent to lithium titanate: a new method for long term immobilization of 137Cs

“…A great number of transition metal hexacyanoferrates (II) have been studied for their prospective use for selective removal of 137 Cs from the liquid nuclear wastes. One of the most promising ion exchangers is titanium hexacyanoferrate, which has been used to remove 137 Cs from the high, medium and low level liquid waste and other radioactive solutions [ 17 , 18 ]. It is known that in alkaline solutions insoluble ferrocyanide is converted to the corresponding oxides [ 17 ].…”

Ion exchange in zeolites. Part 4.—Hydrolysis and trace134Cs+exchange in K- and Na-mordenite

“…(2)] and the concentrations of suspended particles as determined above, the trace 134Cs+ equilibria observed after centrifugation or 3 nm filtration, can now be described by eqn. (14) [Fig. 2(a)].…”

Synthesis and characterization of cobalt ferrocyanides loaded on organic anion exchanger

“…Some results are reported for the formation of macro porous ion exchange beads by mixing ferrocyanide powders with liquid organic exchangers and polymerizing it [7]. One procedure to react porous gel spheres such as titanium oxide with ferrocyanide solution to convert the oxide into the corresponding ferrocyanide is also reported by some scientists [8,9]. Many investigators have used several types of support materials such as silica gel [10][11][12] to develop metal ferrocyanide with large stable particles.…”
