Transport of carboxymethyl cellulose stabilized iron nanoparticles in porous …

Abstract. Carboxymethyl cellulose (CMC) can facilitate in situ delivery of zero-valent iron (ZVI) nanoparticles in contaminated aquifer. This work investigated transport of CMC-stabilized ZVI nanoparticles (CMC-Fe) using column breakthrough experiments and model simulations. The nanoparticles (18.1 ± 2.5 nm) were transportable through four saturated model porous media: coarse and fine glas…
