乙醇胺、NaOH混合液的电位滴定分析法

Electrical potential titration of Ethanolamine and NaOH Mix

比较了一次滴定与两次滴定结果，确定了两步滴定分析方法，通过精密度、准确度试验，证明方法可靠。

The two steps titration method has been set up through its comparison with the single step one.The method so adopted shows reliable through its precision and accuracy tests.
