Effect of natural organic matter effec on fate and transport of engineered nanoparticles
This study characterized Ohio river natural organic matter during winter and summer seasons, and demonstrated the effects of these natural organic samples on stability and transport of cerium oxide nanoparticles in saturated porous media. OR-NOM samples that were characterized by thermal analysis, Fourier transfer solid state neutron magnetic resonance spectrometer and elemental analysis showed to have structural and compositional differences from standard humic acid. This study explored the effects of OR-NOM in enhancing the transport and breakthrough of ceria nanoparticle 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 nanopraticles.
