摘要
用盐酸、硝酸分解样品,高氯酸冒烟析出钨酸分离钨,在硝酸、高氯酸介质中采用原子吸收光谱仪测定钨精矿中铅,方法简便快速,干扰少,准确度、精密度均好,测定下限可达到0.005%,适用于钨精矿中铅的测定。
The determination of lead in the tungsten concentrates mineral by atomic absorption spectrometry in the nitric acid and perchloric acid is investigated.The sample is dissolved by hydrochloric acid and nitric acid.The tungsten is separated by the deposition of tungstic acid with the perchloric acid.The detection limit obtained for lead is 0.005%.This method enjoys the advantages of high speed,few interference,accuracy and precision.
