Abstract
Objective To establish a fast detection method for multi-elements in mineral water by inductively coupled plasma-mass spectrometry(ICP-MS).Methods The detection condition was optimized and 6 metallic elements(Cu,Zn,Cd,Ag,Pb,Ba) in mineral water were simultaneously detected.Results The detection limit was 0.004 7-0.47 μg/L and recovery rate was 93.8%-108.1%.Conclusion In comparison with traditional method of atomic absorption,the method is accurate,fast,and convenient with extensive linearity range and high sensitivity.The result is satisfactory.
