Extraction of U(VI) from Aqueous Media by Layer Double Hydroxides Intercalated by Chelating Agents

The comparison research is made of the efficiency of removing U(VI) compounds from wastewaters synthesized by hydrotalcite-like sorbents: intercalated by hexamethylenediaminetetracetic and ethylene diaminetetracetic acids. It has been shown that the efficiency of sorbents for extracting U(VI) from wastewaters at pH 8 is determined by stability of its complexes with chelate ligands located in the interlayer space of layered double hydroxides.
