Selective flow-injection determination of aniline and m-nitroaniline in mixtures containing isomeric nitroanilines and aniline

Abstract

Operating conditions for the selective flow-injection determination of aniline and 3-nitroaniline in the presence of isomeric nitroanilines as 5,7-dichloro-4,6-benzofuroxan derivatives of test compounds are determined by varying the flow composition. The analytical range is 0.35-17.5 μg/mL for aniline and 1.5-30 μg/mL for 3-nitroaniline. The detection limit of aniline in the presence of nitroanilines is as low as 0.2 μg/mL. © 1998 MAEe cyrillic signK Hayκa/Interperiodica Publishing
