Abstract
An emission spectrographic method employing de-are excitation has been described for the determination of Bi, Cr, Cu, Fe, Mg Mn, Ni, Pb, Si and Zn in aluminum base materials. The samples were dissolved in nitri c acid, dried and converted to oxide form by heating in a tube furnace at 900 degrees C under oxygen atmosphere before analysis. Treated sam ples were mixed with graphite in 2:1 ratio and excited in 10 Amp dc-ar e for 30 seconds. The lowest detection limits for different elements l ie between 10 and 40 ppm.
