摘要
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。
A new versatile electrolytic cell was devised which is beneficial in that mercury pollution can be excluded completely. The device is easy to manipulate and gives good precision and accuracy in anode stripping voltammetry on a rotating glasscarbon electrode. In the application to the analysis of water of diverse origins, the cell excels furnace AAS in its very high sensitivity of heavy metals, such as Cd, Pb, Cu, and Zn.
