초록
매달린 수은전극에서 N-Benzoylphenylhydroxylamine을 리간드로 사용하여 흡착벗김 전압전류법으로 PIPES 완충용액에서 극미량의 바나듐을 정량하였다. 이 때 흡착전위 +0.15V, 흡착시간 10초에서 바나듐의 검정곡선은 $10{\sim}70{\mu}g/L$ 범위에서 직선성을 나타내었다. 그리고 다른 금속 이온의 영향은 없었다.

Abstract
Trace vanadium was determined by Adsorptive stripping voltammetry with HMDE in PIPES buffer solution. N-Benzoylphenylhydroxylamine was used as a ligand. The calibration curve of vanadium was linear over the range of $10{\sim}70{\mu}g/L$ on accumulation potential of +0.15V and on accumulation time of 10 sec. The various metal ions did not interfere with the determination of vanadium(V) in this case.
