FTIR and Synchronous Fluorescence Heterospectral Two-Dimensional Correlation Analyses on the Binding Characteristics of Copper onto Dissolved Organic Matter
University of Science and Technology of China · CAS Key Laboratory of Urban Pollutant Conversion
Abstract
Dissolved organic matter (DOM) is known to form strong complexes with heavy metals and thus governs the distribution, toxicity, bioavailability, and ultimate fate of heavy metals in the environment. The relevant aspects of metal-organic interactions remain unclear because the metal binding functionalities in DOM are substantially nonuniform and the availability of the models is limited. In this work, two-dimensional correlation spectroscopy (2DCOS) integrated with synchronous fluorescence and infrared absorption spectroscopy was used to explore the binding process of copper to DOM. A series of heterogeneous binding sites in humic acid (HA), a representative DOM, and the subsequent subtle changes of these sites…
