As a laboratory technician, you are presented with an aqueous sample that was collected from highway runoff during a rain storm. You are to quantitatively analyze for Pb, Zn and Cu in the aqueous sample using flame AAS. As you can imagine, there will be many other elements and compounds present in the solution. How would you best determine the concentration of the analytes in the presence of the other elements and compounds?
