A reversed phase partition column pretreated by a cationic surfactant was employed. Although this ligand forms thermodynamically stable complexes with various metal ions, only peaks of Pb^<2+> and Cd^<2+> were detected with the ligand-centered emission in the HPLC due to the emissive activity and kinetic stability in the dissociation reaction. The detection limits obtained were 1.5 × 10^<-8> and 3.3 × 10^<-9> mol l^<-1> for Pb^<2+> and Cd^<2+>, respectively., text, application/pdf}, pages = {140--144}, title = {Direct fluorescence detection of Pb^<2+> and Cd^<2+> by high performance liquid chromatography using 1-(4-Aminobenzyl)ethylenediamine-N,N,N’,N’-tetraacetate as a pre-column derivatizing agent}, volume = {1104}, year = {2006}, yomi = {サイトウ, シンゴ and ホシ, スワル} }
