Release of organic chelating agents from solidified decontamination wastes
Data are presented on the release of organic complexing agents from solidified simulated decontamination resin wastes. The organic acids included were: ethylenediaminetetraacetic acid, oxalic acid, citric acid, picolinic acid, and formic acid. Additionally, samples were tested which contained the decontamination reagent LND-101A and a simulated resin waste expected with the LOMI (low-oxidation-state-metal ion) reagent. Ion-exchange resins equilibrated with the reagents were solidified in cement and vinyl ester-styrene. The release of the organic acids was measured using the standard procedure ANS 16.1, ''Measurements of the Leachability of Solidified Low-Level Radioactive Wastes.'' The data suggest that the release of the acids may follow a diffusion mechanism. Data are also presented which indicate that immersion in water can affect the compressive strength of solidified simulated decontamination resin wastes. Analytical methods are described which can be used to measure organic acids in waste form leachates. Ion chromatography proved to be the most versatile of the methods examined.
