Cadmium Adsorption Data for Pristine and Activated Bamboo Biochar

Supplementary file 2 from a study by H. Lalhruaitluanga, uploaded to figshare in 2026. The dataset contains experimental results on the adsorption of Cadmium(II) from aqueous solution using pristine and chemically activated biochar derived from Melocanna baccifera bamboo. It includes equilibrium and kinetic analysis data, with reported maximum adsorption capacities of 15.15 mg/g for pristine and 24.39 mg/g for KOH-activated biochar.

Use Cases

• Modeling adsorption isotherms based on the Langmuir isotherm parameters mentioned in the description.
• Analyzing adsorption kinetics based on the Pseudo-second-order model and rate-controlling steps described.
• Comparing the effect of chemical activation (KOH vs. H3PO4) on adsorption performance as detailed in the study.
• Investigating the influence of pH on adsorption efficiency, with optimal removal noted at pH 5.

Strengths

• Includes specific maximum adsorption capacities: 15.15 mg/g for pristine and 24.39 mg/g for activated biochar.
• Describes controlled experimental parameters such as pH and activation methods (KOH, H3PO4).
• Data is associated with a published research methodology including FTIR analysis and batch experiments.

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 very small (65.7 KB), indicating limited scope.
