✦ Synopsis

PicoIinic acid was used as an on-column chelating agent for the reversed-phase liquid chromatographic separation of manganes&I), copper(H), nickel(B), cobalt(H), cadmium(III and xi&II. The effects of picolinic acid concentration, pH and type and content of organic sohrent on the retention of transition metal ions have been studied. The possibility of sensitive UV detection of complexes at 235 mn is demonstrated. Data on the use of studied system for the determination of some metal ions in a gaIvanic bath waste water are presented.
