| 中文摘要 | a method for the specific determination of cobalt based on reversed-phase liquid chromatography with amperometric detection via on-column complex formation has been developed. a water-soluble chelating agent, 1-(2-pyridylazo)-2-naphthol-6-sulphonic acid (pan-6s), is added to the mobile phase and aqueous cobalt solutions are injected directly into the column to form in situ the cobalt-pan-6s chelate, which is then separated from other metal pan-6s chelates and subjected to reductive amperometric detection at a moderate potential of -0.3 v. because the procedure eliminates the interference of oxygen and depresses the electrochemical reduction of the mobile phase-containing ligand pan-6s, by virtue of the quasi:reversible electrode process of the cobalt-pan-6s complex, a low detection limit of 0.06 ng can be readily obtained. interference effects were examined for sixteen common metal species, and at a 5- to 8000-fold excess by mass no obvious interference was observed. the feasibility of the method as an approach to the specific analysis of cobalt in a hair sample has been demonstrated. |
