The material decontamination factors reached in equilibrium desorption with a solution of a complexing agent and with an aqueous suspension of a competing sorbent are formally equivalent. The example of the sorption of cesium ions onto Berlin Blue shows that the competitive sorption is a promising approach to decontamination of soils and building materials. |
