Experimental Data for Fe(II) Oxidation by O₂ in Sulphuric Acid Media (pH −1.5 to 8.0; 5–65 °C)

This repository contains the raw experimental data and processed kinetic results supporting the study: A Coupled pH–Temperature Logistic Rate Law for Fe(II) Oxidation by O₂ in Sulphuric Acid Media (pH −1.5 to 8.0; 5 to 65 °C) and Its Implications for Sulphate-Rich Waters The datasets comprise Fe(II) oxidation experiments performed over a wide range of pH (−1.5 to 8.0) at five temperatures (5, 25, 40, 50, and 65 °C). The raw data include time-resolved Fe(II) concentration measurements used to determine oxidation kinetics. The processed datasets contain the corresponding kinetic parameters and calculated reaction rates used for model development and statistical analysis.
