摘要：

The possibility of using a piece of gas chromatographic capillary column as a tubular denuder for Isolation and enrichment of organic pollutants present in air was studied. The partition coefficients (K-fs) of typical organic pollutants (benzene, chlorobenzene, toluene) between the gaseous phase and the denuder sorption layer were determined and effects of analyte concentration in the gaseous phase and gas flow rate on partitioning were studied. The partition coefficients were found to he constant in the studied range of concentration and gaseous mixture flow rate. A piece of a capillary column coated with polydimethylosiloxane can he used as a tubular denuder.
