85 % sulfuric acid ( 1 ) is avoided, the sensitivity is twice that obtained when glacial acetic acid(3) is used, and a source of error introduced with the use of 2,6-dichlorophenolindophenol (4) to oxidize ascorbic acid before formation of the osazone is eliminated. The resulting method has been found to be quite satisfactory with respect to sensitivity, specificity, facility, and recovery of added ascorbic acid.
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.
