Fluorescent Carbon Nanoparticle Transport in Sand Columns with Hydrophobicity Effects

Data from 2023 sand column experiments and modeling investigate the effect of hydrophobicity on fluorescent carbon nanoparticle transport. The dataset includes outlet concentration measurements for nanoparticles synthesized at four pyrolysis temperatures and tested across three sand types under saturated and unsaturated conditions. Daniel May of Stanford University authored the accompanying paper, which includes results from inert tracer tests and three transport models.

Use Cases

• Modeling nanoparticle breakthrough curves based on hydrophobicity and sand type data
• Comparing nanoparticle retention under saturated versus unsaturated flow conditions described in the experiments
• Calibrating transport models using the included two-kinetic sites model raw output
• Analyzing the relationship between pyrolysis temperature and nanoparticle recovery in porous media

Strengths

• Includes data from experiments testing four specific pyrolysis temperatures (190C, 210C, 230C, 250C)
• Covers three distinct sand types (Fine, Medium, Coarse) and two moisture conditions (saturated, unsaturated)
• Provides modeling results for three different transport models and raw output for the selected best model

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Last update date is unknown; freshness unverified
