Determination of trace Pb and Bi in pure copper by graphite furnace atomic absorption spectrophotometry(GFAAS)

GENG Dong-fang,LI Yan,LI Jian-fang(Ningbo Branch of China Academy of Ordnance Science,Ningbo 315103,China)  
In order to control the impurities content in pure copper,it is important to determine trace Pb and Bi in pure copper.The ashized and atomized temperature can be enhanced when Cu is used as a matrix modifier.It is determined to select the pure copper as standard sample.The relative standard deviation of Pb is 6.32%,Bi is 3.53%.It is simple and quick to determine trace Pb and Bi in pure copper using the graphite furnace atomic absorption spectrophotometry.
