摘  要:
使用微波消解方法处理磷铁矿样品,建立一种使用连续光源原子吸收法(AAS)快速测试磷铁矿中的K、Na、Pb、Zn、Cu含量的方法.该方法的检出限为0.0004~0.0050 mg/L,测定结果与标准值的相对标准偏差为0.82%~1.48%,加标回收率为99.4%~102.5%,具有抗干扰能力强、线性范围宽、精密度高、结果准确等特点,适用于磷铁矿中多种金属元素的快速分析.

摘  要:
The content of potassium, sodium, lead, zinc and copper in phosphosiderite are determined by microwave digestion and continuous light source AAS. The detection limit of this method is 0.000 4-0.005 0 mg/L,the relative standard deviation of determination results and standard values is 0.82%-1.48%, and the adding standard recovery rate is 99.4%-102.5%. This method has the characteristics of strong anti-interference ability,wide linear range, good precision and high accuracy, which is suitable for the rapid analysis of multiple metal elements in phosphosiderite.
