Method for quickly tracing floating oil on surface water based on three-dimensional fluorescence spectrometry

The invention discloses a method for quickly tracing floating oil on a surface water surface based on a three-dimensional fluorescence spectrometry, which is characterized by comprising the following steps: preparing a plurality of mixed oil solutions according to different concentration proportions to form a correction sample set, measuring the three-dimensional fluorescence spectrum of the correction sample set, analyzing the three-dimensional fluorescence data by adopting a parallel factor algorithm, and determining the traceability of the floating oil on the surface of the surface water. Obtaining characteristic fluorescence peaks of a plurality of oils and establishing corresponding identification models; the method comprises the following steps: rapidly extracting oil slick of an actual water body by using a low-density polypropylene composite oil absorption material, re-dissolving the oil slick by using an organic solvent, determining a three-dimensional fluorescence spectrum, and substituting the thre
