Description:
We investigated the effects of background solution chemistry and residence time within the soil column on the transport of aqu/C60 through saturated ultrapure quartz sand columns. Aqu/C60 breakthrough curves were obtained under different pore water velocities, solution pHs, and ionic strengths. Retention profiles along the columns were also obtained. Transport of aqu/C60 through the columns was simulated using a modified form of the 1-D advective-dispersive transport model with terms for non-equilibrium particle attachment and detachment rates, as well as for a limiting particle retention capacity of the collectors. This study represents an initial step in understanding the transport of fullerene aggregates in porous media and lays the groundwork necessary for studying fullerene transport in more complex, environmentally relevant systems.
