摘要:
The present invention relates to the use, for extracting molecular iodine, of a material comprising a first material corresponding to the following formula (I): M(L) x [M'(CN) 4 ] in which: - M and M' are chosen, independently of one another, from Fe and Ni; - x is a positive integer; and - L is an organic ligand chosen from optionally aromatic, heterocyclic compounds comprising at least one nitrogen atom. Use in the field of spent fuel reprocessing.
摘要:
The invention relates to a solid nanocomposite material including: nanoparticles of a metal coordination polymer with CN ligands including M n+ cations, where M is a transition metal, and n is 2 or 3; and [M' (CN) m ] x- anions, where M' is a transition metal, x is 3 or 4, and m is 6 or 8; said M n+ cations of the coordination polymer being bonded by an organometallic bond to an organic group of an organic graft chemically bonded to the inside of the pores of a porous glass medium. The invention also relates to a method for preparing said material, to a method for fixing an inorganic pollutant, such as radioactive caesium, contained in a solution by placing said solution in contact with said material.
摘要:
