适用于各种极谱分析用的多功能、通用型的W—Ⅱ型电解池,较好地防止了汞对环境的污染,使分析人员避免了汞中毒的危害。在旋转玻璃碳电极进行阳极溶出伏安法分析时,用该电解池不但保证了良好的精密度和准确度,还使操作手续变得简便,生产效率提高,分析成本降低。直接测定水质中ppb级Cd、Pb、Cu、Zn等重金属元素,各项技术指标超过了石墨炉无火焰原子吸收法。 极谱分析所使用的电解池,种类较多,但适用于各种极谱仪的通用型多功能的电解池,尚未见文献报导。本文介绍了一种W-Ⅱ型电解池(图1、2),其特点是,外参比电极室能一室多用,根据 Suitable for all kinds of polarographic analysis of multi-functional, universal W-Ⅱ type electrolytic cell, to better prevent mercury pollution of the environment, so that analysts to avoid the harm of mercury poisoning. The rotating glassy carbon electrode for anodic stripping voltammetry analysis, the use of the electrolytic cell not only ensures good precision and accuracy, but also make the operation easier, production efficiency, lower analysis costs. Direct determination of ppb level in the water quality of heavy metals such as Cd, Pb, Cu, Zn, the technical indicators over graphite furnace without flame atomic absorption method. There are many kinds of electrolytic cells used in polarographic analysis, but there is no literature report on a versatile multi-purpose electrolytic cell suitable for various kinds of polarography. This article describes a W-Ⅱ type electrolytic cell (Figure 1,2), which is characterized by an external reference electrode chamber can be more than one room, according to
