Data for: Utilizing high pH of geopolymers for activation of persulfates in aqueous phenol abatement

This dataset contains the underlying numerical data for the figures of the article "Utilizing high pH of geopolymers for activation of persulfates in aqueous phenol abatement" (Desalination and Water Treatment 2026;328:101852) and its supporting information. The study evaluated metakaolin-based alkali-activated geopolymer foam as a flow-through medium that supplies alkalinity for the activation of peroxydisulfate (PDS) and peroxymonosulfate (PMS) in the abatement of phenol from ultrapure water and from phenol-spiked tertiary municipal wastewater. The deposit comprises a Microsoft Excel workbook of seven worksheets covering phenol abatement, oxidant decomposition, radical scavenger experiments, and electron paramagnetic resonance (EPR) spectra, together with the raw X-ray diffraction files in the native Rigaku formats. A README document describes the file contents, the experimental conditions, the units, and the abbreviations used. Phenol abatement experiments were performed in a flow-through column packed with geopolymer foam, at an initial phenol concentration of 10 µM, oxidant doses of 0.6 to 2.4 mM PMS or 1.2 to 4.8 mM PDS, a flow rate of 300 mL h⁻¹, and an empty bed contact time of approximately 30 min.
