Abstract
In this paper a dynamic method to determine gas-water partition coefficients (K-values), respectively Henry's Law Constants (HLCs), is presented. The K-values, the HLCs and the water solubilities (S) for some lower chlorinated dibenzodioxins (PCDDs) were measured. The values of the gas-water partition coefficients ranged between 8,16 E-4 for 1,2,3,4-TetraCDD up to 2,40 E-3 for 2,7-DiCDD, the Henry's Law Constants from 2,02 Pa m3/mol to 5,96 Pa m3/mol respectively. The guaranteed equilibrium and the verification of the mass balance confirm the high reliability of our results.
