摘要：

A normal-phase high-performance liquid chromatography (HPLC) method for the selective determination of vanadium with N-phenylbenzohydroxamic acid (PBHA) is described. The V-v-PBHA complex was preconcentrated by solvent extraction into trichloromethane and injected on to a silica gel column for HPLC, with a mobile phase of methanol-trichloromethane (3 + 97) containing 9.4 X 10(-4) mol dm(-3) PBHA. The detection limit for vanadium by the proposed method was 8.3 and 1.7 mu g dm(-3) for phase-volume ratios of 5:1 and 20:1 (aqueous-to-organic), respectively. Vanadium has been determined in clam tissue with satisfactory precision.
