摘要：

The high-performance liquid chromatographic behaviour of Co2+, Zn2+, Cu2+, Cd2+ and Pb2+ on a column packed with iminodiacetic acid-bonded silica (250 x 3 mm i.d.) was studied using solutions of dipicolinic acid as eluent. Optimum separation was achieved when the concentration of dipicolinic acid in the eluent was 1 x 10(-3) mol l(-1) and the eluent pH was 3.0. The possibility of the sensitive indirect spectrophotometric detection of transition metals at 295 nm is demonstrated. The detection limits for the investigated metals are in the range 0.1-1 mu g ml(-1). The determination of zinc and lead in industrial waste waters was performed.
