Cadmium Adsorption Data for Blueberry Waste Biochar from Batch Experiments

4.13 mg g⁻¹ is the maximum cadmium adsorption capacity reported for biochemically activated biochar. The dataset contains results from batch experiments evaluating the removal of cadmium from aqueous systems using biochar derived from blueberry pruning waste. It was authored by Jonathan Suazo-Hernández and last updated on April 28, 2026.

Use Cases

• Model adsorption kinetics based on the Elovich model mentioned in the description
• Compare adsorption capacities of chemically, biologically, and biochemically activated biochars
• Analyze the effect of surface area (S_BET) on adsorption performance
• Study desorption behavior over multiple cycles for adsorbent reusability

Strengths

• Specific surface area (S_BET) values are provided for four biochar types, ranging from 6.2 to 64.2 m² g⁻¹
• Adsorption capacity is quantified, with a maximum of 4.13 mg g⁻¹ for the biochemically activated biochar
• Model fit statistics (r² and χ²) are reported for kinetic and isotherm models

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
