New type of sorbent, based on the complexing properties of polyethyleneglycols, with high selectivity for Ba and Sr is described.
The dependences of Kd on the initial concentration of HNO3 for Ba, Sr, Eu, Ce, Cs and Na were studied. The capacity of two model sorbents for uptake of Cs and Sr is given. The properties
of the sorbents are compared with those of the ammonium salts of heteropolyacids.
