Abstract
Inductively coupled plasma-optical emission spectrometry (ICP-OES) was applied to the determination of uranium in the eluate that was obtained in the extraction process of uranium from sea water.
Optimization of operating parameters of ICP-OES and spectral line profiles were examined. A linear calibration curve up to 30μEg/ml and a detection limit of 0.02μEg/ml for standard solutions were obtained by using the uranium 409.01nm line.
Uranium in the acidic eluates from amidoxime resin was determined by ICP-OES. Analytical results agreed with those obtained by spectrophotometry with Arsenazo III and fluorometry. As a result, ICP-OES was found to be useful for the rapid determination of uranium in the eluate.
