随着我国环保工作的迅速发展,痕量重金属(如铜、铅、镉、锌等)的分析日益需要。为了适应环保分析所提出的灵敏、简便和自动化等要求,我们研制了一种自动反向极谱仪,用于水及其他样品中痕量重金属的分析。反向极谱技术,又叫阳极溶出极谱技术,近十年来,已广泛运用于痕量重金属的测定。它的优点在于仪器设备简单,灵敏度高,但不足处是要大量使用汞或汞盐,以及操作烦琐,不便于自动化。如何发扬反向极谱技术之长,克其之 With the rapid development of environmental protection in our country, the analysis of trace heavy metals (such as copper, lead, cadmium, zinc, etc.) is increasingly needed. In order to meet the requirements of environmental analysis such as sensitivity, simplicity and automation, we developed an automatic reverse polarography instrument for the analysis of trace heavy metals in water and other samples. Reverse polarographic technique, also known as anodic dissolution of polarographic techniques, the past decade, has been widely used in the determination of trace heavy metals. Its advantage is the simple equipment, high sensitivity, but the downside is to use mercury or mercury salts in large quantities, as well as cumbersome operation, not easy to automate. How to carry forward the technology of reverse polarography, g
