Abstract: Nickel-based alloy (0.25 g) was dissolved in 10 mL of HCl - HNO3 (6:1). The solution was evaporated to dryness and evaporation was repeated with 7 M HNO3 (5 ml). The residue was dissolved in 7 M HNO3 (5 ml) and 2.3 M HF solution (2 ml) and the solution was diluted to 50 mL with water. A portion of this solution (240 µL) was injected into a stream of 0.7 M HNO3 - 0.09 M HF (0.6 mL min-1) and passed to the ICP-MS instrument (operating conditions described). Detection limits for Tl, Pb and Bi were 0.001, 0.04 and 0.007 ppm, respectively. Results agreed with certified values.
