摘要
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.
