摘要
为了测量成膜剂中主要成分的含量,采用氧化还原滴定与配位滴定相结合的方法,先利用Ce4+的氧化性测其含量,再利用Zr4+与Ce3+、Al3+分别与EDTA形成的配合物稳定常数差值较大,通过控制酸度分步滴定。操作方便、快速,结果准确。
In order to determine the content of main components of filmogen treating metal surface,using Redox Titration and Complexometry, first using the oxidation of Ce^4＋ to determine its content, then successive determine content of Zr^4＋.Ce^3＋,Al^3＋ by controlling the pH. The result is tested to be accurate and reliable.
