Abstract: The Henry's law constant for carbazole was experimentally determined between 5 and 35°C using a gas-stripping technique. The following equation was obtained for dimensionless Henry's law constant (H′) versus temperature (T, K):lnH′=-3982(T,K)-1+1.01 Temperature-dependent octanol-air partition coefficients (KOA) and supercooled liquid vapor pressures (PL, Pa) of carbazole were also determined using the GC retention time method. The temperature dependence of KOA and PL were explained by the following:logKOA=4076/(T,K)-5. 65logPL(Pa)=-3948(T,K)-1+11.84 The gas and particle-phase carbazole concentrations measured previously in Chicago, IL in 1995 was used for gas/particle partitioning modeling. Octanol based absorptive partitioning model consistently underpredicted the gas/particle partition coefficients (K p) for all sampling periods. However, overall there was a good agreement between the measured Kp and soot-based model predictions.
