Arsenic Adsorption Data for TiO2, Fe2O3, and Composite Sorbents

Raw materials characterisation and adsorption data support a research paper on surface complexation modelling of arsenic. The dataset includes adsorption isotherms, pH edges, and potentiometric titration data for arsenic(III) and arsenic(V) on three sorbent materials. Data was primarily collected by Jay Bullen between 2016 and 2019 at Imperial College London.

Use Cases

• Calibrating surface complexation models based on the provided adsorption isotherm and pH edge data.
• Comparing the adsorption performance of single-component (TiO2, Fe2O3) and composite (TiO2-Fe2O3) sorbents.
• Preparing input files for the FITEQL software using the included templates and example files.
• Validating characterisation results by cross-referencing data from multiple techniques like BET, XRD, FTIR, and XPS.

Strengths

• Includes data from multiple characterisation techniques (BET, XRD, FTIR, zeta potential, DLS, LEIS, XPS, XRF).
• Covers both arsenic(III) and arsenic(V) adsorption across different experimental conditions (isotherms, pH edges).
• Provides templates and examples for FITEQL input/output, aiding reproducibility.

Limitations

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