介绍了稀土金属中微量钨的测定方法研究 ,着重研究了试样的分解。采用把金属钨转化成三氧化钨的方法 ,解决了金属钨难分解的问题。通过标准加入回收、标准偏差等实验 ,说明分析方法在准确度和精密度上已达到了分析质量要求。
The method for the determination of trace tungsten in rare earth metals is introduced. The decomposition of the sample is emphatically studied. Use of tungsten into tungsten trioxide method to solve the problem of difficult decomposition of tungsten metal. Through the standard to join recycling, standard deviation and other experiments, indicating that the accuracy and accuracy of analytical methods have reached the analysis of quality requirements.
