摘要
凯氏定氮法是国际经典的测定样品中总氮含量的方法,选取了一种国产催化剂和两种进口催化剂进行催化效率的比较,结果表明,国产催化剂催化效率优于其它两种进口催化剂,且成本较低,是样品中总氮含量快速定量测定的高效催化剂。
Kjeldahl determination is the classic method of determination of total nitrogen content in the samples, this article compared the efficiency of the domestic catalyst and two kinds of imported . The result shows that the domestic catalyst is better than the other two imported, and the cost is low, is a high efficient catalyst in fasty quantitative determination of total nitrogen content in the samples.
