FIELD: chemistry.
SUBSTANCE: method consists in obtaining cyclic voltampergrams, with the subsequent calculation of the nanoparticles concentration in the sample according to the analytical peak current values, wherein for a single analysis from 30 to 100 mcl of the liquid sample applied to the indicator electrode surface is used, and the analytical peaks are represented by the signals in the area of +0.1 V for Au in 0.1 M HCl, +0.7 V for Ni in 0,1 M KCl, -0.14 V for Cu in 0.1 M H2SO4.
EFFECT: proviiding the possibility of eliminating the sorption conditions influence of nanoparticles from the liquid sample on the accuracy of their detection, and reducing the analysis time.
