| Abstract: | Objective:To establish a method for determine of Pb,Cd and Hg in fish muscle by inductively coupled plasma optical emission spectroscopy(ICP-OES).Methods: The samples were grinded to muddy shape,added with HNO3 and H2O2,and treated with closed microwave at 180℃ for 30 min,then the extraction was determined by ICP-OES with transverse type.Results: The Pb,Cd and Hg were determined in four samples.The relative standard deviations(RSDs) of Pb,Cd and Hg were below 10%,and the recoveries of spiked samples were 92%～101%.Conclusion: The method with high accuracy and precision was convenient,rapid and sensitive for Pb,Cd and Hg analysis in fish muscle. |
