Effect of water activity on carbon dioxide transport in cholinium-based ionic liquids with carbonic anhydrase

摘要

The present work reports a study of the affinity of carbon dioxide towards biocompatible cholinium-based ionic liquids, aiming the development of a sustainable process for carbon dioxide removal. Moreover, the enhancement on carbon dioxide transport by the addition of carbonic anhydrase, able to catalyze the reversible reaction of carbon dioxide with water, is also evaluated.
