METHOD FOR SELECTIVE SEPARATION OF IONIC SPECIES FROM IONIC SOLUTION BASED ON IONIC HYDRATED SIZE

摘要

The present invention relates to methods for selective separation of ionic species from an ionic solution based on said species' ionic hydrated size, the method comprising, inter alia, passing an ionic solution comprising ions having distinct hydrated sizes, through an electrode capacitor assembly comprising at least one carbon-based electrode which is modified with negatively or positively charged surface groups. Further provided is a method for selective separation of ionic species from an ionic solution comprising passing the ionic solution comprising a first positively charged ion and a second positively charged in through an electrode capacitor assembly, wherein the first modified electrode comprises carbon modified with sulfonate surface groups.
