摘要
介绍了一种采用原子荧光光谱仪测定钼酸铵中痕量铅的测定方法,该方法研究了检出限、精密度、加标回收率等,在选定的试验条件下,相关系数r=0.999 7,检出限为 0.000 030%,精密度为 5.19%,样品加标回收率在96.11%～103.58%,说明方法具有灵敏度高、线性关系好、精密度高、分析结果准确可靠等优点,可应用于钼酸铵中铅的准确测定.
Abstract
A method for the determination of trace lead in ammonium molybdate by atomic fluorescence spectrometer are introduced.The detection limit,precision and recovery rate of the method are studied.Under the selected test conditions,the correlation coefficient r=0.999 7,the detection limit is 0.000 030%,the precision is 5.19%,and the recovery rate of the sample is 96.11%～103.58%.The method has the advantages of high sensitivity,good linear relationship,high precision,accurate and reliable analysis results,and can be applied to the accurate determination of lead in ammonium molybdate.
