Ion exchange reaction of [18F]fluoride with an oxidized carbon surface

[18F]Fluoride was trapped from [18O]water in high yield by ion exchange on a microporous carbon prepared by controlled oxidation to produce a cationic surface with an exchange capacity of about 350 [mu] equiv/g. The [18F]fluoride could be recovered by displacement with aqueous K2CO3. The cationic carbon offered a dimensionally rigid matrix of high thermal stability. It was characterized with respect to chemical reactivity and selectivity for anion exchange.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/29626/1/0000715.pd
