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).

本数据集源自探究疏水性对多孔介质中荧光碳纳米颗粒（fluorescent carbon nanoparticles, FCN）运移行为影响的砂柱实验与模拟研究。数据集包含多组实验中FCN的出口浓度（相对于入口浓度），这些实验涵盖了测试四种不同热解温度（190℃、210℃、230℃及250℃）合成的FCN的回收效果，以及FCN通过三种不同粒径砂柱（细砂、中砂、粗砂）时的回收情况。本研究在饱和与非饱和条件下开展柱实验，以探究孔隙含水量对FCN滞留行为的影响。此外，本数据集还收录了惰性溴化物示踪剂的测试结果（文件：May_et_al_Column_Experiment_Outlet_Concentrations.xlsx）。本数据集同时纳入了三种不同运移模型对FCN实测穿透曲线的模拟结果，以及惰性溴化物示踪剂的模拟结果（文件：May_et_al_Breakthrough_Curve_Modeling.xlsx）。本数据集还提供了经证实可最优复现实测穿透曲线的双动力学位点模型的原始输出文件（文件：May_et_al_Two_Kinetic_Sites_Model_Raw_Output.zip）。本数据集亦包含采用扫描电子显微镜（scanning electron microscope, SEM）对三种砂样开展的砂粒表面表征结果（文件：May_et_al_Sand_Surface_Characterization_SEM-DATA.zip）。如需获取更多细节，请参阅以下论文：May, D.F., B.
