Significant Difference

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.

Carrier Gas Flow

A fixed-size simplex has been used to determine the optimum conditions for the simultaneous determination of arsenic, selenium, and antimony by hydride generation and inductively coupled plasma emission spectrometry. The variables selected for the simplex were carrier gas flow rate, rf power, viewing height, and reagent conditions. The detection limit for selenium was comparable to the preoptimized case, but there were twofold and fourfold improvements in the detection limits for arsenic and antimony, respectively. Precision of the technique was assessed with the use of artificially prepared water samples.
