摘要：

Cu(II) Co(II) and Fe(II) in pharmaceutical preparations were determined using precolumn derivatization and solvent extraction with 2-acetylpyridine-4-phenyl-3-thiosemicarbazone (APPT) as complexing reagent. Liquid chromatography (LC) was carried out on a reversed phase C-18, column. The complexes were eluted isocratically with acetonitrile-water containing sodium acetate and tetrabutyl ammonium bromide as ion-pairing agents. The results obtained were compared with those using atomic absorption.
