Fluorescence Reaction AmongN-(Phenyl)-N-(4-Methylquinolinyl) Amine Derivatives, Hydrogen Peroxide and Cobalt(II), and its Application

Abstract

Abstract The fluorescence reactions among seven N-(phenyl)-N-(4-methylquinolinyl)amine derivatives, hydrogen peroxide as a redox agent and cobalt (II), in the presence or absence of various surfactants, were systematically investigated. The order of the relative fluorescence intensities (R. fl. Int.) of these fluorescence products were N-(4′-hydroxyphenyl)-N-(4-methylquinolinyl)amine (IV), N-(2′-hydroxyphenyl)-N-(4-methyl quinolinyl)amine(11) > 3′-hydroxy-4 ′-carboxyphenyl)-N-(4- methylquinolnyl)amine(MQAB)(VII))> N-(3′-hydroxyphenyl)-N-(4 methylguinolinyl)amins(III) > N-(phsnyl)-N-(4-methylquinolinyl)amine(I)) >N-(4′-carboxyphenyl)-N-(4-methylquinolinyl)amine(V) >N-(3′-carboxyphenyl)-N-(4-methylquinolinyl)amine(VI)- fluorescence products. Especially, the R.fl.Int. using (IV) in the presence of cationic surfactants inbssic media was most large and stable, and asimple, rapid and eensitive spect- rofluorometric method for the determination of cobalt(II) using (IV) and hydrogen peroxide in the presence of tr...
