Abstract
Picolinic acid was used as an on-column chelating agent for the revers ed-phase liquid chromatographic separation of manganese(II), copper(II ), nickel(II), cobalt(II), cadmium(II) and zinc(II). The effects of pi colinic acid concentration, pH and type and content of organic solvent on the retention of transition metal ions have been studied. The poss ibility of sensitive UV detection of complexes at 235 nm is demonstrat ed. Data on the use of studied system for the determination of some me tal ions in a galvanic bath waste water are presented.
