A method for the determination of Cr, Zn, Fe, Mn, Ti, Cu and Mg impurity elements of alloy aluminum of ICP-AES was studied. Working conditions were optimized. The method is simple, rapid, precise and convenient. The relative standard deviation is less than 6.3%. The recovery is 94%-105%. The results are satisfactory.
