description The invention discloses a method for separating humic acid and quantitatively analyzing polycyclic aromatic hydrocarbon based on fluorescence-correlated sectioning spectrum. The method comprises the following steps: preparing experimental single-component polycyclic aromatic hydrocarbon and mixed aqueous solution samples of humic acid and polycyclic aromatic hydrocarbon with different concentrations; scanning the fluorescence spectrums of the experimental samples under different excitation wavelengths to obtain one-dimensional dynamic fluorescence spectrums of the samples; the method comprises the following steps: determining a characteristic fluorescence wave band A according to a fluorescence spectrum of a single-component polycyclic aromatic hydrocarbon aqueous solution; carrying out asynchronous two-dimensional correlation calculation on the obtained one-dimensional dynamic fluorescence spectrum of the mixed sample by taking excitation wavelength as external disturbance; the obtained asynchronous two-dime
