“…Literatures show that not only PB but also several other PB-analogue complexes [M x Fe 1−x (CN) 6 ] y− , where M is Ni 2+ , Cu 2+ , Zn 2+ , Co 3+ , and Mn 3+ 17 – 32 , are effective for Cs + removal in freshwater and in some cases in seawater. These complexes having hetero metal M n+ ion are synthesised by addition of MCl 2 or 3 to a solution of potassium ferrocyanide.…”

“…The adsorption capability of PB for alkali metal ions is in the order of Cs + ≫ K + ≧ Na + . In addition to original PB, Cs + adsorption is reported also to PB analogues containing various hetero metal ions such as Ni 2+ , Cu 2+ , Co 3+ , Mn 2+ and Zn 2+ 17 – 32 as partial substituents for Fe ions in the lattice. It is not easy to decide which hetero metal ion is better than others for Cs + adsorption, since literature experiments were carried out under different conditions and on various sample matrices.…”

A new adsorbent Cu-Perussian blue@Nanodiamond (Cu-PB@DND) for Cs+ removal was prepared and characterized with IR, SEM, X-ray diffraction, particle size analysis, and zeta-potential. The adsorbent consists of a core of aggregated detonation nanodiamond (DND) particles with the surface treated with Cu-PB. Cesium adsorption was studied in two modes; a co-precipitation mode and a batch mode. In the co-precipitation mode, DND, CuCl2, and K4[Fe(CN)6] were added sequentially to a Cs+ solution in diluted artificial seawater. In the batch mode, adsorbent Cu-PB@DND was dispersed into a Cs+ solution with stirring. The distribution coefficient (Kd) of the co-precipitation mode was 8.8 × 107 (mL/g) at Cs+ 6.6 ppm in 0.07% seawater. The Kd value of the batch mode was 1.3 × 106 (mL/g). Precipitation of Cs+-incorporated particles was complete, and post filtration was not necessary. Excess copper and iron ions were completely removed and were not detected in the supernatant. The adsorption data for Cu-PB@DND were analyzed by assuming Langmuir isotherm and a good fit was obtained with a maximum adsorption capacity Qmax of 759 mg/g. The co-precipitation method was also applied to soil-treated wastewater.

“…Although it looks like the adsorption of Cs between pH 4-8 decreased, when considering the range and unit of y axis, it does not indicate the meaningful decrease. However, the q e value for Cs rapidly decreases above pH 11 because of the decomposition of copper ferrocyanide, which is caused by OH -ions [33].…”

Sorption of cesium ions from aqueous solutions by multi-walled carbon nanotubes functionalized with copper ferrocyanide

In this study, copper ferrocyanide-functionalized, multi-walled carbon nanotubes (MWCNT-CuFCs) were synthesized. The MWCNT-CuFCs exhibited a high capacity for sorbing Cs ? from aqueous solutions because of their strong affinity for Cs ? and high specific surface area. The sorption capacity of the MWCNT-CuFCs for Cs ? was dependent upon the initial pH of the solution. The sorption ability of the MWCNT-CuFCs for Cs ? was maintained even in the presence of co-existing ions (K ? and Na ? ). To determine the degree of Cs ? desorption from the MWCNT-CuFCs, a column-based desorption experiment was performed.

“…For selective removal of Cs-137, two main groups of materials are widely used: Granulated and composite transition metal (Ni, Co, Cu) ferrocyanides [7][8][9] and resorcinol-formaldehyde resins (RF-resins) [10,11] related to the phenol-formaldehyde thermoreactive group of resol-type polymers. The main disadvantage of transition metal ferrocyanide sorbents is a low chemical stability in alkaline media [12,13], which results in fast degradation of the materials.…”

Porous ion-exchanging resorcinol-formaldehyde resins were prepared by removing an inorganic template (CaCO3) and by polymerization of a highly concentrated emulsion with toluene as a dispersing phase. As compared to original resorcinol-formaldehyde resins, the porous one is characterized with higher values of internal diffusion, providing exceptional purification coefficients. However, the amounts of the introduced CaCO3 and toluene have to be below 10 wt.% and 25 wt.%, respectively, to avoid fast degradation of the ion-exchanger. Under dynamic conditions, average purification coefficients in the model solution of Cs-137 are twice higher than those of the non-porous sample. The prepared porous ion-exchange resin can be used in cases when high Cs-137 uptake from liquid media should be realized at increased rates of solution percolation.
