• 論文の詳細を見る

• A novel reversed-phase partition liquid chromatography-photometric detection system for the determination of trace amounts of vanadium is described. A strongly colored vanadium(V)-2-(8-quinolyl azo)-5-N,N-diethylaminophenolato chelate is separated on a μBondapak-CN column using an aqueous acetonitrile mobile phase and is detected at 540 nm(0.02 absorbance unit full-scale). Because the other common cations give no resolved peaks on the chromatogram under the conditions, the determination of vanadium at 5 × 10-<-8> to 1 × 10^<-6> mol dm^<-3> level is free from their interferences in case of the total concentration of such cations less than 5 × 10^<-5> mol dm^<-3>.
