Abstract: Anionic, hydrophilic carbon (Fe/C) and poly(acrylic acid)-supported (Fe/PAA) zerovalent iron nanoparticles were studied as a reactive material for the dehalogenation of chlorinated hydrocarbons in groundwater and soils The transport of Fe/C nanoparticles was studied by elution through columns packed with model soils from different regions of the USDA soil textural triangle, and was compared to that of unsupported Fe nanoparticles The Fe/C and Fe/PAA particles form colloidal suspensions that settle very slowly (hours to days) in water Their anionic surface charge facilitates transport through soil- and sand-packed columns Elution lengths from column breakthrough studies were compared with calculations based on the Tufenkji−Elimelech model (Environ Sci Technol 2004, 38, 529) It can be concluded from this comparison that nanoparticle diffusion is the dominant filtration mechanism, and that Fe/PAA and Fe/C particles have sticking coefficients on the order of 036 and ≤007, respectively, in sand and 0
