S-nZVI@BC/PS System Performance for Crude Oil Soil Remediation

A 946.5 KB document by Jin Zheng, last updated April 14, 2026, details the synthesis and application of a biochar-supported sulfidated nanoscale zero-valent iron composite (S-nZVI@BC) for activating persulfate to remediate crude oil-contaminated soil. The data likely contains experimental results on material characterization, degradation efficiency under varying parameters, and impacts on soil microbial communities and plant germination.

Use Cases

• Modeling the relationship between composite parameters (biochar loading, S/Fe ratio) and crude oil degradation efficiency based on described experimental results.
• Analyzing the shift in soil microbial community structure after remediation treatment as mentioned in the description.
• Comparing the contributions of different reactive species (SO4–∙ and ∙OH) to hydrocarbon degradation based on the reported findings.
• Assessing the effect of the remediation system on plant germination rates, specifically for Elymus dahuricus, as indicated in the results.

Strengths

• Reports a specific maximum crude oil degradation efficiency of 90.14% under defined experimental conditions.
• Details specific optimal parameters, including a 25% biochar loading rate, S/Fe molar ratio of 1:10, and activated carbon particle size of 0.83 mm.
• Published under a permissive CC-BY-4.0 license, allowing for reuse and redistribution.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (946.5 KB), indicating limited scope, likely containing summary results rather than raw experimental data.
