Research Progress of Organic Matter Based on Three-Dimensional Fluorescence Spectroscopy-Parallel Factor Analysis ( EEM-PARAFAC)
Three-dimensional fluorescence spectroscopy-parallel factor analysis ( EEM-PARAFAC) not only has the advantages of low cost of three-dimensional excitation emission matrix( EEM) , high sensitivity and rapid analysis, but also has the ability to interpret and analyze data more systematically and comprehensively. It is widely used in the related research of natural organic matter ( NOM ) analysis. EEM-PARAFAC can quickly track and determine the source of pollutants. This article reviews the sources, molecular structure and composition of organic matter. Through analysis and comparison, it is believed that organic matter degradation and organic matter can be obtained from the molecular structure and functional group level. The law of adsorption and complexation has guiding significance for the study of changes in the external environment, the growth of animals and plants, and the removal of pollutants, and has a wide range of application prospects.
