The viability and limitations of inductively coupled plasma atomic emission spectrometry (ICP-AES) for trace characterization of concentrated EDTA solutions are determined Qualitative detection of elemental impurities based on multielement scans, semiquantitative estimates of impurity levels obtained by comparison of results with calibration graphs in the 1 to 5 µg/mL range, and quantitative analyses via standard addition methods involving EDTA solutions doped with trace metals in the 01 to 10 µg/mL, and in the 001 to 016 µg/mL ranges are reported Applications of the method to the analysis of EDTA, purified by recrystallization, and to the monitoring of EDTA solutions, electrolyzed at the mercury cathode, are described Mercury cathode electrolysis is superior to the recrystallization method only in the case of removal of Cd, Cu, and Fe The recrystallization procedure provides the greater advantage of reducing the levels of a broader range of trace elements than was possible by electrolysis Both methods reduce amenable trace elemental impurities in EDTA solutions to the 100 ng/mL level or below

Automated Platform

Presented here is a novel automated method for determining the trace element composition of bulk thorium by inductively coupled plasma–optical emission spectroscopy (ICP-OES). ICP-OES is a universal approach for measuring the trace elemental impurities present in actinide-rich materials; however, due to the emission rich spectrum of the actinide, a separation from the trace elements is warranted for spectrochemical analysis. Here, AG MP-1 ion exchange resin was utilized for retention of the Th matrix, while allowing the trace element impurities to be separated prior to subsequent analysis using ICP-OES. After demonstrating the separation on traditional gravity-driven columns, the methodology was transitioned to an automated platform for comparison. This automated platform utilizes syringe-driven sample and solvent flow and can collect the trace element and thorium fractions in separate locations. While reducing the sample size (500 µL, 1.5 mg of Th), maintaining the overall separation efficiency (recoveries >95%), and illustrating the sample throughput ability (n = 10+), this automated methodology could be readily adopted to nuclear facilities in which the determination of trace elemental impurities in Th samples is warranted.
