Whatman DE-53, a weak anion-exchange resin, was chosen because it has excellent physical properties compatible with the microcentrifuge spin column method and a high exchange capacity ([greater than or equal to] 2 meq/g dry weight).
Ion exchange is attractive because the perchlorate group has a very high affinity for common polystyrene strong-base anion-exchange resins.
Strong anion-exchange resins are not usually considered for fluoride removal because of their low capacity and relatively high cost.
Other qualitative and quantitative methods have been reported (11-14), many of which include prepurification of PBG with anion-exchange resins, but all rely on the derivatization of PBG with Ehrlich-type reagent, which is not specific for PBG, and thus have the potential for false positives.
