A novel technique to determine the rate constants for the gas-phase reactions of low-volatile compounds with OH radical using a relative-rate method in CCl4 liquid phase-system
For low-volatile aromatic compounds, a good linear relationship was found between the rate-constant ratio for the liquid-phase reaction with NO3 radical in CCl4 and that for the gas-phase reaction with OH radical when naphthalene was employed as a reference compound. Based on the relationship, the rate constants for the OH radical reaction have been successfully determined for fluoranthene and pyrene, which are important airborne polycyclic aromatic compounds.
