Abstract: Nitric acid is used to dissolve the high purity silver ingot, with ICP-AES to determine the 19 trace elements as Al, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Ni, Pb, Au, Pd, Pt, Rh, Si, Sn, Te and Zn within. To obtain accurate experimental results, select appropriate instrument conditions and analysis spectral lines, then measure the curves to match the silver content. The recovery and accuracy of results prove to be satisfactory. Silver is separated as AgCl precipitate and the trace element contents in the supernatant is determined. The results show that the silver precipitation has little effect on the determination. Therefore, the test can be achieved without the matrix matching of silver. This method can thus eliminate silver interference and reduce sample testing cost.
