Immobilization of Metal Hexacyanoferrate Ion-Exchangers for the Synthesis of Metal Ion Sorbents—A Mini-Review

Metal hexacyanoferrates are very efficient sorbents for the recovery of alkali and base metal ions (including radionuclides such as Cs). Generally produced by the direct reaction of metal salts with potassium hexacyanoferrate (the precursors), they are characterized by ion-exchange and structural properties that make then particularly selective for Cs(I), Rb(I) and Tl(I) recovery (based on their hydrated ionic radius consistent with the size of the ion-exchanger cage), though they can bind also base metals. The major drawback of these materials is associated to their nanometer or micrometer size that makes them difficult to recover in large-size continuous systems. For this reason many techniques have been designed for immobilizing these ion-exchangers in suitable matrices that can be organic (mainly polymers and biopolymers) or inorganic (mineral supports), carbon-based matrices. This immobilization may proceed by in situ synthesis or by entrapment/encapsulation. This mini-review reports some examples of hybrid materials synthesized for the immobilization of metal hexacyanoferrate, the different conditionings of these composite materials and, briefly, the parameters to take into account for their optimal design and facilitated use.

“…Fig. 9 shows that with increase of anode potential during latexes deposition from +0.3 V to +0.9 V the thickness of the film abruptly increases, most likely, due to the aggregation of latex particles in solution at potential +0.7 V and +0.9 V [22]. Since the content of ferrocyanide in composite materials directly depends on the amount of latex deposited, the highest ferrocyanide loading degrees were obtained at polarization +0.9 V (Table 3).…”

“…Also, because adsorption is sometimes reversible, adsorbents can be regenerated. Transition metal (Ni, Zn, Cu, Fe, Co) hexacyanoferrates (MHCFs) are of the most frequently applied adsorbents for the treatment of radiocaesium wastewaters due to the high affinity for caesium ions and other radionuclides [11].…”

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Insignificant change in the current after 100 cycles of durability test indicated the CuHCF NPs film is relatively stable, suggesting the battery-type column has a long service life for Cs removal from wastewater.
