<P>PROBLEM TO BE SOLVED: To provide a carbon dioxide separation membrane excellent in both selective absorption and diffusion of a water absorbing polymer and carbon dioxide, a method for manufacturing the same, and a membrane module using the same. <P>SOLUTION: The carbon dioxide separation membrane includes a gel membrane containing the water absorbing polymer, a carbon dioxide carrier and water, and a support for supporting the gel membrane, wherein a pH on an absorption side surface which is a side where a mixing gas containing the carbon dioxide on the gel membrane is supplied is higher than a pH of a diffusion side surface which is an opposite surface of the surface of the absorption side surface. <P>COPYRIGHT: (C)2013,JPO&INPIT |
