The use of ferrocyanide Zn/Al-hydrotalcite for the sorptive concentration and radiometric determination of 137Cs in waters

Resumo

A sorbent based on Zn/Al-hydrotalcite intercalated by hexacyanoferrate (II)-ions is proposed for ¹³⁷Cs concentration and its further radiometric determination in natural waters. Parameters for the optimal sorptive extraction of radiocesium from waters under static conditions and direct radiometric measurements have been determined. The use of ferrocyanide sorbent is shown to provide a good potential in analytical schemes of ¹³⁷Cs concentration from waters with high salt background.
