1.Therefore,the quick and accurate determination of copper,silver,arsenic in lead and lead alloys was realized with the RSD of 0.34%-0.49%. The recoveries of Cu,Ag and As were 99.2%-116.7%,93.3%-101.1% and(98.3%)-116.0% respectively.
2.Compared with chemical method ore other typed instrumental methods,this instrument is characterised by high sensitivity ( DL: 3.9×10 -3 μg/ml),nice reappearanc( RSD :<2.0%) and quick analytical velocity. In addition,the determinations of silver,and copper are successfully made at the same time.
