Abstract: The invention relates to environmental protection, namely, to the decontamination of soil, ground, sand, ion-exchange resins, slag and other solid granular wastes. It can be applied in nuclear power plants, radio-chemical industries, and territories affected by anthropogenic catastrophe and accidental spills of liquid radioactive waste. The colloid-resistant nano sorbent for decontamination of solid granular materials comprises reaction product, combined with an equivalent amount of cations from the group of transition metals and hexacyanoferrate anion, which are precursors of sorbent formed among stable carboxyl polymer colloid.
