FIELD: chemistry.
SUBSTANCE: stripping voltammetry measurements are made directing a visible light laser with wavelength 0.63-0.65 mcm, power 3-5 mW onto the surface of a working electrode which is immersed in a background solution for not less than 55 minutes before taking measurements and continuously during voltammetry measurements.
EFFECT: high sensitivity, high efficiency of electrochemical processes for accumulation of a defined metal.
