以铜离子作为滴定剂或被测对象的容量分析方法称为铜滴定法。 Cu~(2+)能与一系列试剂定量地进行络合、沉淀和氧化还原反应。铜盐溶液很稳定,很容易制备和标定,因此围绕Cu~(2+)可进行一系列测定,是一个值得开拓的容量分析领域。但由于Cu~(2+)的化合物常有很深的颜色,缺乏较好的化学指示剂,因此铜的很多定量反应不能形成新的容量分析方法。示波极谱的出现,解决了这个问题。现在我们可以在新技术的帮助下,探索这一新的领域。
Copper ion as a titrant or the volumetric method of measuring the object is called the copper titration method. Cu 2+ can complex with a series of reagents quantitatively, precipitation and redox reaction. The copper salt solution is very stable and can be easily prepared and calibrated. Therefore, a series of determinations about Cu 2+ can be carried out, which is worth exploring in the field of volumetric analysis. However, because Cu 2+ compounds often have deep color and lack of good chemical indicator, many quantitative reaction of copper can not form a new capacity analysis method. The emergence of oscilloscope polarography solved this problem. Now we can explore this new field with the help of new technologies.
