Hello everybody, I am looking for a disgestion procedure of Pb-alloy, so that we can measure the elements with ICP-OES. Pb should be removed, that it doesn't contaminate the system. So far we used HCl for digestion, but the results weren't very good. Elements of interest are: Sn Sb Bi Cu Cd As Zn Ni Ag Tl Al Te I hope anyone can help me. Thank you very much!
