摘要

Objective: To develop a method for simultaneous determination of Pb, Cd, Cu, As and Ba in salt by inductively coupled plasma mass spectrometry. Methods: After dissolution with 0.1% HNO3, salt was directly determined by inductively coupled plasma mass spectrometry. Results: The detection limit was 0.008-0.044mg/kg, the RSD was less than 3.5%, recoveries were 96.0%~106%, and the results of analyzing standard materiel were satisfactory. Conclusion: This method is simple, sensitive and accurat, and can simultaneously determinate Pb, Cd, Cu, As and Ba in salt.
