钼精矿中钾含量分析方法改进

Improvement of Potassium Content Analysis Method for Molybdenum Concentrate

用微波密闭消解的方式替代电热板消解样品,以原子吸收光谱法通过人员比对、方法比对、实验室间比对的方式对钼精矿样品定值;定值样品经粉末压片后建立X-荧光光谱测定曲线,对生产样品进行钾含量分析。经过比对,荧光分析值与化学分析值相符,方法具有较好的准确度与精密度,可满足大批量钼精矿中钾含量的分析。

In this paper,microwave closed digestion was used to replace the electrothermal plate digestion,and atomic absorption spectrometry was used to determine the molybdenum sample by personnel comparison,method comparison and laboratory comparison.X-fluorescence spectrometry was established to determine the potassium content of the sample.After comparison,the fluorescence analysis value is consistent with the chemical analysis value,and the method has good accuracy and precision,which can satisfy the analysis of potassium content in large quantities of molybdenum concentrate.
