| Abstract: | The determination of vanadium in the surface water was performed by inductively coupled plasma- mass spectrometry （ICP - MS）. After the water sample acidified by nitric acid, we Optimize the instrument condition and direct determinate vanadium content in the solution with ICP - MS. The results showed the good linearity in the range from 0. 0μg/L to 100μg/L. The detection limit for vanadium by this method was 0. 04 μg/L and the recovery for vanadium was 98.4% - 100. 2% with relative standard deviation of less than 1.0%. This method has the characteristics of low detection limit, high accuracy and good precision , which is suitable to be used to measure vanadium in the surface water and drinking water. |
