Abstract |
Carbazole has been detected in some airborne particulate samples. Two spectrophotometric methods for the determination of carbazole are introduced. Beer's law was obeyed from 4 to greater than 90 microgram of carbazole in the 3-methyl-2-benzothiazolone hydrazone and p-nitrosophenol procedures. Both methods can be used for the estimation of carbazole in the benzene extracts of airborne particulates. Two new spot tests for carbazole are also introduced. With the p-nitrosophenol test 0.4 microgram of carbazole can be detected. This test can be applied to air samples. In strongly alkaline solution 0.2 microgram of carbazole can be detected through the brilliant blue fluorescence of the anion. |
