The absorption process in the vicinity of the gas-liquid interface was visualized in the system where CO_2 was absorbed into amine solvents and diffused toward the interior of liquid phase. From the interferogram obtained by phase shifting interferometer, the increasing of concentration field instability in the liquid phase was observed as time advanced or pressure of the gas phase was increased. This was because the density of the amine absorbing CO_2 increased and the liquid was affected by the gravitational force. Therefore, pseudo diffusion coefficient was obtained larger than that of the molecular diffusing system. It was considered that the self-generated instability enhanced the mass transfer of CO_2 in the vicinity of interface and liquid phase.
