脉冲溶出伏安法中汞膜碳纤维电极性能的研究

采用脉冲阳极溶出伏安法,研究了汞膜碳纤维电极测定痕量金属离子的行为,并与汞膜玻碳电极和悬汞电极进行了系统的对比,显示了碳纤维电极在静止态溶液、极稀溶液、有机溶液和双电极体系中具有特殊的优越性。本文对该电极的制作,预处理和实际测试条件进行了探讨。

Analytical Behavior of Mercury Film Carbon Fiber Electrodes in Differential Pulse Stripping Voltammetry

This paper reports the behavior of trace metals at mercury film carbon fiber electrodes in differential pulse stripping voltammetry. In comparison with glassy carbon electrodes and hanging mercury drop electrodes, carbon fiber electrodes show many advantages in quiescent solution, dilute solution, organic solution and a double-electrode system. This paper discusses the preparation and pretreatment of carbon fiber electrodes and the measurement conditions.
