To quickly and accurately determine the heavy metals in cut filler, a DRC-ICP-MS method for determining Cr, Ni, As, Se, Cd, Cs, Hg and Pb in cut filler is established with microwave digestion. The results showed that the recoveries of these elements ranged from 85.06% to 119.54% with the relative standard deviations below 10% and the limits of detection of 0.24 to 70.05 ng/L.
