- Abstract
The generation of gas mixtures of polar organic compounds at the level of their maximum permissible concentrations (several μg/m3) by continuous gas extraction from aqueous solutions with known concentrations in combination with dilution with a diluent gas flow was studied. The distribution coefficients of phenol, isomeric cresols, nitrobenzene, and C4–C6 alkanols between aqueous and gas (nitrogen) phases necessary for this study were determined. A two-stage generation technique based on the saturation of a sorbent (activated carbon) with an extractant gas flow with a given concentration of target components followed by their desorption by a flow of pure extractant gas was proposed.
