ATOMIC EMISSION SPECTROMETRIC DETERMINATION OF ARSENIC ANTIMONY,BISMUTH,LEAD,TELLURIUM AND VANADIUM IN SMOKE OF TAIL GAS FROM COPPER SMELTING

AES with D.C electric are excitation was applied to the determination of As,Sb,Bi,Pb,Te and V in smoke of tail gas evolved from copper smelting.Working parameters,including working conditions of the spectrometer,the choice of analytical spectral lines,ratio of buffer reagents to sample (in mass) suitable for mixing and etc,were studied and optimized.Three samples were analyzed by the method proposed,giving values of RSD′s (n=7) for the 6 elements in the range of 2.8%-23.3%.
