| Abstract: | The application of inductively coupled plasma mass spectrometry for water samples （surface water, drinking water, etc. ） , copper, zinc, selenium, arsenic, cadmium, chromium, lead, iron, manganese and other trace dements were analyzed. The results showed that the detection limit was 0.01-0.78μg/L, the relative standard deviation of parallel samples was 0.6% to 7.9%, and the recovery of added standards in water samples ranged from 90.5% to 103%. The method was rapid, simple, linear range and good detection limits and accuracy. |
