概要

• 論文の詳細を見る

• Trace amounts of carbazole and anthracene in dibenzofuran can be simultaneously determined by measuring the synchronous fluorescence intensities at 336 and 381 nm respectively. The determination limit is 2 ppm. For the application of this method to the practical samples containing interfering impurities, a zone-melting technique was applied successfully to remove the impurities prior to the determination. The recoveries of carbazole and anthracene were 99 and 92% respectively.
