Abstract Determination of Mg, re, and Zn by inductively coupled plasma emission spectroscopy (ICP) and by the official flame atomic absorption spectrophotometric (FAA) method were compared. Samples were acid digests of commercial fertilizers. Neither matrix effects nor spectral interferences were encountered in the ICP analyses. Linear regression shows that the slopes obtained by plotting ICP results vs FAA results for each element differ from unity by less than 5%.
