Abstract: Accurate determination of trace impurities in ammonium molybdate is the key to product quality control. In order to provide reliable data support for the quality testing and product control of ammonium molybdate, the contents of trace elements Mg, Al, Ca, Cr, Fe, Mg, Ni, Cu, As, Cd, Sd and Pb in ammonium molybdate were analyzed by online internal standard-inductively coupled plasma mass spectrometry（ICP-MS）. The samples were dissolved in hydrochloric acid-nitric acid-hydrofluoric acid. The effec... More
