摘要

Three different systems including HNO₃-HF,HNO₃-HF-HCl and HNO₃-HF-H₂O₂ were used to dissolve soil standard material of GBW 07405 with microwave and a PTFE sealed tank on electric heating plate respectively.This method meets the requirements of the quantitative analysis of the heavy metals Cr,Ni,Cu,Zn,As,Cd and Pb for large soil sample batches.This work can efficiently and accurately provide the scientific basis for risk assessment and maintenance for topsoil.
