Laboratory experiments were conducted to investigate the behavior of CO2 microbubbles (MBs) and the process of CO2 dissolution under atmospheric pressure by injecting CO2 MBs into deionized water and groundwater. The number of CO2 MBs increased dramatically after starting the CO2 MB generator, thereby increasing the concentration of dissolved CO2. The concentration of dissolved CO2 induced by CO2 MB injection increased approximately four times more rapidly than when CO2 was bubbled. The concentration quickly reached a maximum value which coincides with the theoretical saturation concentration of CO2(aq) solution. Larger CO2 bubbles were injected after the CO2(aq) solution became saturated. The increase in the concentration of dissolved CO2 was accompanied by reductions in both the pH and the density of (CO3)2—. In addition, the high concentration of the CO2(aq) solution was maintained for a relatively long time.<BR>These experimental results will assist in developing a practical system for CO2 MB injection, which is a method developed in Japan for geologically storing CO2.
