    • Seasonal Variation of Natural Organic Matter influence on the fate and transport of engineered nanomaterials

    Metadata Updated: November 12, 2020

    This study characterized Ohio river natural organic matter (NOM) during winter and summer times, and demonstrated the effects of these NOM samples on stability and transport of ceria nanoparticles in saturated porous media. Ohio river NOM samples that were characterized by thermal analysis, spectroscopic method, solid state NMR spectrometer and elemental analysis showed to have structural and compositional differences from standard humic acid that is used for laboratory tests, This study explored the effects of Ohio river NOM in enhancing the transport and breakthrough of ceria nanoparticles in moderate (1-10 mM) ionic strength solutions. The enhancement in stability and transport appear to be dominated by the altered electrokinetic properties of the ceria NPs.
