Effect of Hydrophobicity of Fluorescent Carbon Nanoparticles on Transport in Porous Media: Column Experiment Data and Modeling

The data contained here are derived from sand column experiments and modeling which investigate the effects of hydrophobicity on the transport of fluorescent carbon nanoparticles (FCN) in porous media.

The data consist of outlet concentrations (relative to the inlet concentrations) of FCN for a suite of experiments testing the recovery of FCN synthesized using four different pyrolysis temperatures(190C, 210C, 230C, and 250C), as well as the recovery of FCN when passed through three different sand types (Fine, Medium, and Coarse). Column experiments were tested under both saturated and unsaturated conditions to investigate the role of pore water content on FCN retention. Finally, results from tests using an inert bromide tracer are also included (File: May_et_al_Column_Experiment_Outlet_Concentrations.xlsx).

Additionally, the results from modeling the observed breakthrough curves of FCN are included for three different transport models, as well as modelling results for an inert bromide tracer (File: May_et_al_Breakthrough_Curve_Modeling.xlsx).

The raw output files for the two-kinetic sites model that was determined to best reproduce the observed breakthrough curves are also provided (File: May_et_al_Two_Kinetic_Sites_Model_Raw_Output.zip)

Finally, the results of sand surface characterization for three sands using a scanning electron microscope are included (File: May_et_al_Sand_Surface_Characterization_SEM-DATA.zip).
