METHOD FOR DETERMINATION OF CONCENTRATION OF METAL-CONTAINING AEROSOLS IN AERIAL ATMOSPHERE Russian patent published in 2003 - IPC

FIELD: measuring equipment. SUBSTANCE: an ion exchanger, which can be used a crystal of alkalinehalogen crystal, is placed in an aerial atmosphere, concentration of aerosols is conducted in the cavity of the ion exchanger, after that the spectrum of the values of the ion exchanger absorption factor is determined in the valve band within 200 to 360 nn, proceeding from it the values of the wavelengths, at which the maximum of the values of the absorption factor in the maximum are observed, are determined, referring to the wavelength in the maximum the type of metal ion in the metal-containing aerosols is determined, and referring to the value of the absorption factor in the maximum, the concentration of metal-containing aerosols in the tested aerial atmosphere is determined. EFFECT: enhanced operativeness and reduced labor content in detection of metal-containing aerosols in the aerial atmosphere. 2 dwg
