Abstract:An electrically-regenerated electrosorption process known as carbon aerogel CDI has been developed by Lawrence Livermore National Laboratory (LLNL) for continuously removing ionic impurities from aqueous streams. A salt solution flows in an unobstructed channel formed by numerous pairs of parallel carbon aerogel electrodes.Each electrode has a very high BET surface area (2.0-5 .4x1 OGft2 lb-i or 400-1100 m2 g-') and very low electrical resistivity (<40 mQ cm). BET surface areas of 1.3x107 ft2 lb-' (2600 m2 g-'… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
