We also improved the conventional formol-H2SO4 titrimetric method, and applied it into the determinations of the contents of amide nitrogen and total nitrogen in urea nitrate metal complexes.

我们还对传统的甲醛—硫酸法进行了改良，并将新的甲醛—硫酸法运用于硝酸尿素金属络合物中的酰氨态氮和总氮含量的测定中。

The sample assimilated was mensurated by using formol titration method, this method could mensurate protein in batches for having the characteristics of simple operation and fast mensuration.

实验结果表明此方法操作简便、测定速度快，适用于大批量样品的蛋白质测定。
