Materials based on mixed ferrocyanides can be alternative and more promising sorption systems [1].
Materials and Methods To extract Cs-137 from seawater, composite materials based on mixed ferrocyanide Ni-K and Zn-K are synthesized in a composition with a siloxane-acrylate emulsion and polyethylene.
Results and Discussions According to the X-ray diffraction pattern of sorption materials based on mixed ferrocyanides (Fig. 1), the obtained materials have a highly organized crystal structure, as evidenced by the presence of peaks in the X-ray diffraction patterns of the analysed materials.
The phase composition of materials based on mixed ferrocyanides Ni-K and Zn-K is shown in the corresponding figures.
