FIELD: measuring equipment.
SUBSTANCE: method includes measuring intensiveness of lead compound luminescence. Luminescence of lead compounds is excited by electrochemical means on surface of electrode dipped in solution, while anode and cathode pulses are sent in turns to electrode and intensiveness of luminescence is registered, which appears during cathode pulses. On basis of alternation of luminescence, caused by input of sample into flow of background electrolyte, amount of lead in sample is determined.
EFFECT: shorter detection time, possible analysis under normal room temperature.
