| Abstract: | Three digestion methods were investigated to compare their effects on the determination of twelve heavy metal elements(Cr,Co,Ni,Cu,Zn,Mo,Cd,Sn,Hg,Tl,Pb,U) in certified reference materials.The results showed that the efficiency of microwave digestion was better than the other two digestion methods.A mixed digestion system of HNO3-HF-H2O2 was used with a better digestion effect.A method based on inductively coupled plasma-mass spectrometric(ICP-MS) analysis was established for the determination of the twelve ... |
