| Abstract: | The sample was digested with nitric acid and tartaric acid.Copper,silver,arsenic were directly determined by ICP-AES method.Meanwhile,the matrix effect was experimented,the interference of other elements was studied,the solve condition of the sample was discussed in detail.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. |
