“…The K d s increased with hydrothermal treatment, but not with irradiation. Table 24 of Marsh and colleagues (1995) provides further detail for BSC-210, showing Pu K d s of 0.4 mL/g and lower; Superlig-644 had Pu K d s of 0.2 mL/g and lower (Table 35 of Marsh et al (1995)).…”

“…The concentration of 238 Pu remaining dissolved was not reported. The analyzed compositions of the four test solutions, copied from Table 1 of the original report (Marsh et al 1995), show that the pH was relatively low, equivalent to ~0.16 M NaOH without hydrothermal treatment and ~0.01 M NaOH after hydrothermal treatment.…”

“…In prior tests with simulated complexed alkaline waste, Pu uptake onto various ion-exchange media and solid sorbents increased following hydrothermal treatment designed to destroy those complexants (Marsh et al 1995). Table 2 compares the Pu dispositions in the sRF and RF ion-exchange testing with all five actual-waste tests.…”

“…The results of these studies were presented in a series of topical reports (LA-12528, -12654 Rev, -12862, -12863, -12889, -12943, and -13000). Among the radioelements investigated was Pu but only the last of these many reports from this team (Marsh et al 1995) detailed studies for Pu uptake from alkaline solution.…”

“…The CS-100 is a granular weak-acid phenol-formaldehyde cation exchange resin and thus related to the Duolite ARC-359 used in Hanford operations. Marsh et al (1995) prepared a water-diluted "complexed concentrate" simulant waste solution for testing. This waste contained six organic complexing agents -EDTA, HEDTA, NTA, citrate, gluconate, and iminodiacetate.…”
