Abstract

OBJECTIVE To establish a method for determination of 16 rare earth elements in vegetables by inductively coupled plasma mass spectrometry(ICP-MS).METHODS The samples were digested by microwave method and then determined by ICP-MS with indium element as internal standard.RESULTS Relative standard deviations of the method were between 0.2%-3.1%.The recoveries were between 90.5%-113.6%.Detection limits were less than 0.000 1 μg/L.CONCLUSION The method is accurate,sensitive,rapid,simple and is suitable to determinate rare earth elements in vegetables.
