A rapid method for determination of thallium in copper concentrates was established by Inductively Coupled Plasma-Mass Spectrometry. Using hydrochloric acid-nitric acid-hydrofluoric acid-Perchloric acid decomposition of copper concentrates, aqua regia dissolved salts, diluted to the certain volume. As the ion source, the sample solution measured thallium ionization, ions produced by quality analyzer and detector mass spectra obtained by mass analyzer and detector. According to the counting element ion mass to charge ratio, the calibration curve method for the rapid determination of thallium content in solution.
