In this work the conditions for synthesis of copper nanoparticles by sodium tetrahydroborate in the presence of NTF are optimized. It is proved that the most favorable conditions for the reduction of copper in the solutions with its concentration of 2.0∙10-2 mol/l, are created when the concentration of tetrahydroborate sodium is three to four- fold exceeded, the titratable alkalinity is 5.3∙10-2-10.3∙10-2 mol/l, the temperature is 60 °C and the ratio of cation and chelate is equimolar. The method of photon correlation spectroscopy has confirmed the obtaining of copper nanoparticles with hydrodynamic radius of 25 nm, including shell stabilizers. The immutability of the size of bass for at least 72 h has been revealed.
