A direct solid electrothermal atomization atomic absorption (ETA-AAS) method has been developed for the determination of lead in aluminum alloys using standard reference aluminum alloys as solid and solution calibrants for lead. An acceptable agreement with lead certified values has been achieved. ...
any of the alloys for which lead is the base metal. Lead alloys are divided into two main groups, depending on whether the percentage of the alloying element is low or high. The low-percentage group includes alloys made with additions of Fe, Cu, Sb, Sn, Cd, or Ca in concentrations tha...
