FIELD: investigating or analyzing of materials.
SUBSTANCE: method comprises preliminary electrochemical treating of the hard gold-based electrode by means of rotating under positive potential in the solution containing chloride-ions for a given time period. The selenium concentration is determined from the value of the anode current of electrochemical dissolving of selenium.
EFFECT: enhanced sensibility and precision of the method.
