Times Cited Count：0 Percentile：0.01(Chemistry, Analytical)A simple, practical, and reliable analytical method for determination of Na, K, Ca, Sr, and Ba by liquid electrode plasma optical emission spectrometry is developed. Appropriate emission lines for quantification, interferences from co-existing elements, and effect of measurement conditions with cell damage have been investigated. The spike and recovery tests using actual sample have been performed for method validation, and negligible sample matrix effect has been observed. Consequently, the method is successfully applied to several radioactive wastes. The obtained data have been agreed well with data from computer calculation and inductively coupled plasma optical emission spectrometry within 10% difference.

The K, Ca, Mg, Na, Fe, Cr, and Ni in plutonium (Pu) nitrate solution were determined by liquid electrode plasma optical emission spectrometry (LEP-OES). Since the emission line of Pu interfered the emission line of the target element in ICP-OES, removal of Pu was necessary in advance to the measurement. Contrastly, Pu emission lines were not observed, when Pu nitrate solution was measured by LEP-OES. However, emission of K, Ca, Mg, Na, Fe, Cr, and Ni was observed. Therefore each element were determined. It was found that trace elements in Pu nitrate solution can be quantified by LEP-OES without the Pu separation.
