Diclofenac Removal Data Using Waste-Derived Biochar and Laccase Composite

Rita Gouveia's dataset contains experimental results for removing the pharmaceutical diclofenac from wastewater using biochar derived from brewery waste and a biocatalytic composite (BC-LAC). The data includes material characterizations with specific surface areas of 301 m²/g and 191 m²/g for BC and BC-LAC, respectively, and results from batch and semi-continuous operation modes in stirred tank and fixed-bed column configurations. The dataset was last updated on 2026-05-25.

Use Cases

• Comparing adsorption performance based on specific surface area measurements for biochar and its functionalized composite.
• Evaluating the effect of operational parameters like material dose and flow rate on breakthrough curves in semi-continuous systems.
• Assessing the cost-effectiveness of combined adsorption and enzymatic degradation approaches for pharmaceutical removal from wastewater.
• Modeling contaminant removal kinetics in fixed-bed column versus stirred tank reactor configurations.

Strengths

• Material characterization includes concrete metrics like specific surface areas of 301 m²/g for BC and 191 m²/g for BC-LAC.
• Experimental design is detailed, covering batch conditions, stirred tank, and fixed-bed column configurations with varied material doses (0.5–2.0 g L⁻¹) and flow rates.
• Dataset is licensed under CC-BY-4.0, facilitating open reuse and sharing.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description suggests the BC-LAC composite did not present enhanced cost-effectiveness, indicating the data may show limitations for this specific application.
