[Simultaneous analysis of multi-elements in vegetation oils by inductively coupled plasma atomic emission spectrometry].


A simple, accurate and sensitive method for the simultaneous analysis of eleven trace elements (Fe, Cu, Co, Ni, Pb, Al, Zn, Cd, Cr, Mn and Mg) in vegetation oils by ICP-AES has been developed. The oils were digested by H2 SO4 ashing method. The detection limits (MDLs) of the method for the eleven elements were in the range of 0.1-3.6 microg x kg(-1). The… (More)
