The sample was dissolved in a mixture of hydrochloric acid, hydrochloric acid, nitric acid, and perchloric acid. In a hydrochloric acid medium with a diameter of 5%, copper, lead, zinc, and iron in archaeological research samples were determined by inductively coupled plasma emission spectroscopy, overcoming the disadvantages of traditional analysis methods such as lengthy steps and difficult process control. The detection limits of the method are: copper 2.0 μ g/g, lead 3.0 μ g/g, zinc 2.0 μ g/g, iron 10 μ g/g, and the precision (RSD, n=12) is between 1.5% and 12.0% The measured values of this method are consistent with the standard values, and the results are accurate and reliable. The sample processing procedure is simple and fast, with a wide linear range and good analytical reproducibility.
