Determination of arsenic in lead ingots with a flow injection quartz tube atomic absorption spectrometry

WANG Jia-sheng(Fujian Anxi Minhua Storage Battery Co., Ltd.,Anxi,Fujian 362400,China)  
This paper describes a mathod for the determination of arsenic in lead ingots with a flow injection quartz tube atomic absorption spectrometry.Systematic studies are made for the optimum analytical conditions,e.g.the working condition of the instrument,the acidity of sample solution,the interference of co-existing ions and etc.The correlation coefficients of the method is0.9990 %,the detection limit is 0.065 μg·L~(-1),RSD is in the range of 1.9 %~5.4 % and the recovery is in the range of 96 %~102 %.
