Figure 3: Changes in the concentration of cations during gas-water-rock experiments (green triangle = pure CO2 case, red square = 0.1% SO2 case, and blue rhombus = 1% SO2 case) and changes in the concentration of cations in the modeling (green dashed line = pure CO2 case, red dashed line = 0.1% SO2 case, and blue solid line = 1% SO2 case).
