Abstract
Sorption of 131I− and 131IO 3 − from aqueous solutions on porous inorganic sorbents modified with d elements is studied at 25°C. The sorbents modified with Ag, Zn, Ni, Cu, and Co ammoniates are characterized by low distribution coefficients of 131I− and 131IO 3 − (Kd <150 ml g−1 at V/m = 1000). Calcination of the sorbents modified with Ag, Cu, and Zn ammoniates at a temperature above 250°C affects the chemical state of the metals in the sorbent matrix, which is accompanied by slight increase in Kd of 131I− and 131IO 3 − as compared to as-prepared samples. With the γ-Al2O3-based sorbents modified with Ni or Cu, Kd of 131I− and 131IO 3 − is well comparable with that for the Ag-modified sorbents based on MSKG silica gel.
