Compiled literature dataset and process‑based model code for arsenite oxidation by Mn oxides

Independent data from Villalobos et al. (2014), Manning et al. (2002), Nielsen‑Franco & Ginder‑Vogel (2023), Owings et al. (2019), Han et al. (2011), and Tang et al. (2013), used to test model transferability to other MnOx phases and conditions.3. Model code and outputs. PHREEQC input files (.phr) with the full reaction network (site‑specific kinetics, surface complexation, edge‑site renewal).

Simulation outputs for all experimental scenarios (calibration and validation). Simulated sorption‑edge distributions of As(III), As(V), Mn(II), and Zn(II) across pH 2–10 on Mn(IV) and Mn(III) edge sites of manganese oxides.
