摘要
本文提出了测定高炉型渣中氮含量的一种新方法。通过溶样实验,找出了适合于高炉型渣,尤其是含TiO_2的高炉型渣的溶样条件及从渣中分离CN^-和N(Ⅲ)的方法。用分光光度法测定分离出的CN^-和N(Ⅲ)的量,得到该高炉型渣中的总含氮量。通过实验,找出了所研究渣样的最佳测定条件和实际测定中的一些影响因素。
A new method of nitrogen determination in the slag of blast furnace type has been put forward in this article. The dissolving methods and the methods of separating CN~ and N ( III )from the slags have been obtained through dissolving experiments. The CN- and N ( III ) contents in the siags have been determined with spectrophotometric method, so the total content of nitrogen in the slags can be obtained. The optimizing conditions and the factors of influence in nitrogen determination have been found through experiments.
