Abstract

In nitric acid medium,the elements of As,Cd,Fe,Hg,Pb in selenium dioxide by ICP-AES are directly determined.The result shows that nitric acid medium as 0.7 mol/L,selenium content as 7 mg/mL in solution,As,Cd,Fe,Hg,Pb detection limit are 0.060,0.036,0.056,0.021,0.068 μg/mL respectively,the recovery in standard is from 95.24% to 105.64%,relative standard deviation is from 0.0096% to 0.081%.
