Metal-organic complexes

Metal Complexation by Naturally Occurring Organic Compounds (NOOCs) in Aqueous Solution and at the Mineral-Water Interface

Natural waters contain a wide range of naturally occurring organic compounds (NOOCs), including both low molecular weight organic ligands and polymeric humic substances. The transport, reactivity, bioavailability, and toxicity of metals are significantly affected by complexation reactions with NOOCs. In this study, we are using complementary in-situ spectroscopic techniques (XAS, ATR-FTIR, and Raman) in combination with macroscopic speciation measurements to refine our understanding of metal complexation by NOOCs in soil and aquatic environments.
