摘要

The gel particle film of polymer compound particles having amino groups has a large absorption amount and emission amount of acidic gas per unit volume, and has a high absorption rate and emission rate of acidic gas per unit mass, and also has stability. Is expensive. A gas absorber in which this gel particle film is supported on a carrier is useful as an acid gas separation material with high energy efficiency.
