Characterizing the fluorescent properties and copper complexation of dissolved organic matter in saline-alkali soils using fluorescence excitation-emission matrix and parallel factor analysis

摘要

The goals of this study are to identify the individual fluorophore component in dissolved organic matter (DOM) of saline-alkali soils, to determine the binding capacities and stability constants of Cu (II) with fluorescent DOM components, and to analyze the potential impact on the complexation between Cu (II) and DOM in different soil environment.
