Abstract. In this work, stabilized selenium nanoparticles have been synthesized via the interaction of sodium selenite with ascorbic acid in aqueous solutions of sodium carboxymethylcellulose with a degree of substitution of 0.97and a degree of polymerization of 810. The structure and physicochemical properties of sodium carboxymethylcellulose solution containing stabilized selenium nanoparticles have been studied. Formation of the metal complexes due to the donor-acceptor interactions between the carboxymethyl groups of carboxymethylcellulose and selenium nanoparticles has been studied by means of FTIR-spectroscopy. The size and shape of the selenium nanoparticles have been determined by means of atomic force microscopy, dynamic light scattering. It has been stated that the size and shape of selenium nanoparticles depend on the conditions of the reduction reaction and the concentration of sodium selenite in solution of sodiumcarboxymethylcellulose.
