As for the use of hydrogen peroxide instead of perchloric acid in soil digestion in the laboratory,this paper selected 6 representative samples and used graphite digester for digestion,the digestion effect of perchloric acid and hydrogen peroxide was compared.The inductively coupled plasma mass spectrometry was used to detect lead,cadmium,chromium,copper,zinc,nickel and other heavy metals in the digestion solution at the same time.Hydrogen peroxide cannot completely replace perchloric acid.
