• 論文の詳細を見る

• Biphenyl is favorable as a zone-melting medium for the selective separation of small amounts of carbazole and anthracene and a subsequent determination. A definite amount (20–100 mg) of an aromatic sample was mixed with 4 g of purified biphenyl. The mixture was zone-melted 20 times. The two analytes were accumulated in the beginning part of the zone-molten ingot, but many others were eliminated from the part. After being dissolved in xylene along with the biphenyl, carbazole and anthracene could be simultaneously determined up to 10 ng ml<SUP>−1</SUP> by measuring the synchronous fluorescence intensities at 340 and 384 nm, respectively.
