Abstract：ToimprovetheaccuracyandreliabilityofthedeterminationdataofCu，Mn，Zn，andPbheavymetalsinsoil， dynamic microwave digestionmethod was used to process soil samples，combined with InductivelyCoupled Plasma-Atomic Emission Spectroscopy （ICP-AES）method todetermine heavy metalelements，and compared with the national standard method.Researchhas show thatthis method exhibits highaccuracyincomplexsoilsamplesandcanmeetherequirements of soil heavy metal element analysis.
