Abstract
An economical and reliable method for determination of petroleum products (kerosene) in air near the objects of aviation-missile cluster (airfields, test sites of launch vehicles, warehouses of fuel and lubricants) has been developed and tested. Kerosene is preliminarily absorbed from the air with glacial acetic acid, the resulting solution is emulsified in distilled water and photometric study is carried out at 344 or 400 nm in cuvettes with an optical path length of 20 mm. The determination of kerosene is carried out using calibration curves plotted for different grades of aviation and rocket fuel. The interval of measured kerosene concentrations in the air is 25 – 350 mg/m3, the error of determination is less than 20%. The method was tested at a certified laboratory of the Federal State-Funded Budgetary Public Health Facility «Center of hygiene and epidemiology No. 97 FMBA of Russia» and used for monitoring of the air quality in the fuel storage and pumping stations of «Baltimore» airport and manufacturing shop of chemically hazardous production. The results of monitoring of the real objects showed good convergence with the reference method of IR spectrometry.
