Abstract：The hydrofluoric acid, nitric acid and hydrogen peroxide were used as digestion reagent. The gradual temperature rising procedure was adopted. Then, a method for the determination of cadmium, chromium and lead in coal gangue by microwave digestion-inductively coupled plasma mass spectrometry was established. 10 μg/L Rh solution was used as internal standard. 208Pb, 52Cr and 114Cd was used as the determination isotope of lead, chromium and cadmium, respectively. Under the selected instrumental working conditions, the proposed method was applied to the determination of coal gangue samples from different areas. The determination results were consistent with those obtained by graphite furnace atomic absorption spectrometry (GF-AAS) and inductively coupled plasma atomic emission spectrometry (ICP-AES). The relative standard deviation (RSD, n=5) was less than 7 %. The detection limit of method was 0.013 μg/g, 2.00 μg/g and 0.20 μg/g for cadmium, chromium and lead, respectively.
