FIELD: nuclear technique.
SUBSTANCE: method involves treatment of an aqueous medium containing isotopes of alkali-earth metal, transient element or heavy metal of atomic mass less 209 with an organic ligand binding one or some isotopes of element to be separated. Ligand is comprised in resin or as a component of ion-exchange resin carrier or forms complex with isotope and it is retained by nano-filtration membrane. Residue comprising complex of isotopes with ligand is separated from filtrate comprising isotopes not formed the complex. For example, ligand represents N-acetamidostyrene ethylenediamine triacetate of the formula: 
. Invention provides enhancing effectiveness of separation and easy regulating the separation degree. Method is simple, economy and doesn't require volume equipments. Invention can be used in preparing inhibitors or absorbers of neutrons in nuclear reactors.
EFFECT: improved separating method.
