摘要: The detection limits and photoionization thresholds of polycyclic aromatic hydrocarbons their chlorides nitrides on the water surface are examined using laser two-photon ionization single-photon ionization, respectively. methods highly surface-selective, with a high sensitivity for tending to accumulate in natural environment due hydrophobic nature. dependence target molecules physicochemical properties (photoionization relating excess energy, molar absorptivity, octanol-water partition coefficient) is discussed. limit clearly depends product coefficient no clear was found energy. these types formulated.
