- •
Aeration promoted CO2 outgassing thereby increasing pH and Fe(II) oxidation rate.
- •
Kinetic model simulates variations in pH, Fe(II), alkalinity, and dissolved gases.
- •
CO2 outgassing and O2 ingassing rates are estimated as 1st-order asymptotic functions.
- •
Fe(II) oxidation rate is accurately estimated by abiotic homogeneous oxidation rate law.
