用极谱催化波测钼(Ⅵ)有较高灵敏度。本文研究把卷积伏安法应用于钼(Ⅵ)的催化波测定。以钼(Ⅵ)-硫酸-苯羟乙酸-氨酸钾为催化体系,同位镀汞玻璃碳电极为工作电极,快速扫描,用模拟电路把催化电流i进行二阶导数卷积e′=
Polarographic catalytic wave detection of molybdenum (Ⅵ) has a higher sensitivity. In this paper, the convolution voltammetry was applied to the determination of molybdenum (Ⅵ) catalytic wave. Using molybdenum (VI) -sulfuric acid-phenylacetic acid-potassium as catalyst system, the same-position mercury-plated glassy carbon electrode was used as the working electrode and scanned rapidly. The second derivative derivative i of the catalytic current i was simulated with an analogue circuit e ’
