Determination of EDTA and HEDTA in Hanford defense waste by high-performance liquid chromatography

Conference ·
OSTI ID:6508557

A High Performance Liquid Chromatographic (HPLC) method to determine ethylenediaminetetraacetic acid (EDTA) and N-hydroxyethyl-ethylenediaminetriacetic acid (HEDTA) has been developed. The method suffers no significant analytical interferences and has a detection limit of 10/sup -2/M for both EDTA and HEDTA in Hanford Defense Waste (HDW). Actual samples of HDW have been successfully analyzed. The average spike recovery for EDTA and HEDTA was 99% and 100% with relative standard deviations of 4.8% and 2.6%, respectively. Non-routine analytical support is available from the Process Development Group and Research and Engineering. Transfer of this technology to Analytical Laboratories and Quality Assurance (QA) has been initiated.
