Determination of Trace Lead in Ammonium Molybdate by Atomic Fluorescence Spectrometry
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.
