Aug 1, 2000 · Details of reactions between pyrite and water initially equilibrated with the atmosphere (pO 2 = 0.2 atm and pCO 2 = 10 −3.5 atm) were investigated in a closed-system, batch reactor at 25°C and 37°C. The values of dissolved O 2 content (DO), Eh, and pH of the experimental solutions were continuously monitored during the reactions that lasted from ∼30 …
