Аннотация: Abstract The silicon carbide and poly(butadiene-acrylonitrile) rubber (NBR) composite material was used for the first time as adsorbent for gas-phase preconcentration of volatile hydrocarbons. The possibility of the preconcentration of n -alkanes and polyaromatic hydrocarbons from the air by using passive sampling on cartridges packed with this sorbent following by thermal desorption - gas chromatographic determination was demonstrated. The sorption rate of model substances from the air at room temperature and atmospheric pressure was studied. The optimum material for the storage and transportation of the collected samples was selected. The desorption efficiency of model compounds from the adsorbent was investigated. The result of thermo gravimetric analysis of the composite to provide the choice of temperature for the regeneration was given. Soil air at the oil field was analyzed using the developed method. The possibility of multiple use of the composite sorbent for analysis was demonstrated.
