水泥中钾钠测定的改进方法

The improved method of determining potassium and sodium in cement

在水泥行业中测定钾钠普遍采用火焰光度法.本文对该法的实验方案、干扰元素的消除进行了研究,并与国家标准样品进行了对比试验,检测结果误差均符合国家标准要求,满足一般水泥企业常规检验要求.

Commonly, determining alkali metals element in cement adopts the flame luminosity (FL) method. The experiment scheme and the method of eliminating disturbing elements are researched, state standard samples are used in contrast test. The error is less than that provided in national standard. The method can meet routine test requirements.
