Adsorption Performance of Biochar-Montmorillonite Composite for Berberine Removal

231.60 mg·g⁻¹ is the maximum adsorption capacity of a novel biochar-montmorillonite composite for removing berberine from soil. The dataset, authored by Wanzheng Ma and last updated in June 2026, contains experimental results on the composite's performance, regeneration, and adsorption mechanisms. It includes data from characterization techniques like BET, SEM, XRD, FTIR, XPS, and Raman spectroscopy.

Use Cases

• Model adsorption kinetics based on pseudo-second-order and intraparticle diffusion parameters.
• Fit adsorption isotherms using Langmuir, Freundlich, and Temkin models described in the study.
• Analyze the effect of pH on adsorption capacity within the optimal 5–7 range.
• Evaluate material regeneration potential based on the 76.99% capacity retention after five cycles.
• Study adsorption mechanisms like pore filling and π–π stacking using the provided characterization data.

Strengths

• Maximum adsorption capacity is quantified at 231.60 mg·g⁻¹.
• Adsorption performance is characterized across multiple models (pseudo-second-order, Langmuir, Freundlich, Temkin).
• Material regeneration data is provided, showing 76.99% capacity retention after five cycles.
• Mechanistic insights are supported by multiple characterization techniques (BET, SEM, XRD, FTIR, XPS, Raman).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (787.7 KB), indicating limited scope.
