Abstract
A series of samples of Termoxid-35 inorganic sorbent (nickel ferrocyanide applied onto zirconium hydroxide granules) were prepared. The samples have similar chemical composition but differ in the degree of peptization in aqueous solutions. Kinetic curves of 137Cs sorption from aqueous solution demonstrate relationship between the sorbent tendency to peptization and its sorption properties. With an increase in the peptizability of the sorbent, its sorption-selective properties become considerably worse. The sorbent preparation process should involve treatment procedures allowing preparation of the peptization-resistant material.
