2026-07-12 Compiled literature dataset and process‑based model code for arsenite oxidation by Mn oxides doi:10.57760/sciencedb.42273 en This dataset provides a compiled collection of experimental data and a process‑based geochemical model for arsenite (As(III)) oxidation by manganese oxides (MnOx). It contains:1. Calibration dataset. Experimental data from Power et al. (2005), Villalobos et al. (2014), and Fischel et al. (2015), used for model parameter estimation. Includes aqueous As(III), As(V), Mn(II), and Zn(II) time‑series under varied pH, SSA, and As(III)/MnOx ratios.2. Validation dataset. 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. arsenite oxidation; manganese oxides (MnOx); geochemical modeling; redox kinetics Guillaume Herman Baheten Boassen Chao Li Haohao Luo Mengqiang Zhu Henning Prommer Jing Sun Chengshuai Liu EMBARGO https://creativecommons.org/licenses/by-nd/4.0 dataset Science Data Bank
