CO 2 recovery apparatus 10A according to the present invention, an exhaust gas 21 containing CO 2, the lean solution 22 comprising an amino group-containing compound with gas-liquid contact, CO 2 absorbing section for absorbing the CO 2 in the lean solution 22 In the absorption tower 11 provided with 24, the CO 2 contained in the rich solution 23 is separated to regenerate the rich solution 23, and in the CO 2 removal exhaust gas 28 from which CO 2 has been removed by the CO 2 absorption section 24. And a purifying part 27 for removing the amino group-containing compound, wherein the purifying part 31 has a photocatalyst supported on a carrier having an air-permeable gap, and an activating member for activating the photocatalyst. And the power supply unit 33, and the activation member is a pair of electrodes of a first electrode 32-1 and a second electrode 32-2. |
