FIELD: analytical chemistry.
SUBSTANCE: method includes using a polymeric cation-exchange diaphragm, which is impregnated with luminescence complexes of platinum metals with cationic water-soluble porphyrines by submerging it into the water-alcohol solution. The oxygen concentration is determined from the intensity of phosphorescence of the sensor which is in a contact with the fluid to be analyzed.
EFFECT: enhanced sensitivity of sensor.
