A method for simultaneous determination of nine kinds of inorganic elements including Be, B, Ti, Co, V, Ni, Mo, Sb, Ba and Tl in mineral of six different mountains was established by inductively coupled plasma mass spectrometry (ICP-MS). The samples were analyzed directly after equilibration treatment. The results showed that the linearity ranged well among 0-200 ug/L with correlation coefficient above 0.9999.and the limit of detection was 0.03, 0.90, 0.40, 0.07, 0.03, 0.07, 0.06, 0.07, 0.30, 0.10 ug/L。 While the recoveries of spiked samples were between 88-110 % and the relative standard deviation (RSD) were 0 to 0.888 %. The method has simple operation, good reproducibility, no complicated pre-treatment steps, high sensitivity and reliable data, and can provide a reference for scientific selection of drinks to the residents.
