Abstract A method has been developed for the simultaneous determination of Al, Fe, Ca, and Mg in wet-process phosphoric acid by dc argon plasma emission spectrometry. The suppression of Ca and Mg emission by phosphate encountered in flame analyses was nonexistent, and other interferences were minimal. Results obtained by the procedure were compared with those obtained by atomic absorption spectrometry. The paired t-test showed no significant difference between the 2 methods at the 95% confidence level.
