Title: ANALYSES OF HTF-48-12-20/24 (FEBRUARY, 2012) AND ARCHIVED HTF-E-05-021 TANK 48H SLURRY SAMPLES

Abstract

Personnel characterized a Savannah River National Laboratory (SRNL) archived sample of Tank 48H slurry (HTF-E-05-021) in addition to the composite of samples HTF-48-12-20 and HTF-48-12-24, which were both retrieved in February 2012. The combined February 2012 sample is referred to as HTF-48-12-20/24 in this report. The results from these analyses are compared with Tank 48H samples analyzed in 2003, 2004, and 2005. This work supports the effort to demonstrate copper-catalyzed peroxide oxidation (CCPO) of organic content in this material. The principal findings with respect to the chemical and physical characteristics of the most recent sample are: (1) The measured potassium tetraphenylborate (KTPB) solid concentration is 1.76 wt %; (2) Titanium was in line with 2004 and 2005 slurry measurements at 897 mg/L, it represents 0.1535 {+-} 0.0012 wt % monosodium titanate (MST); (3) The measured insoluble solids content was 1.467 wt %; (4) The free hydroxide concentration in the Tank 48H filtrate sample (1.02 {+-} 0.02 M) is close to the Tank 48H limit (1.0 M); (5) Carbonate reported by total inorganic carbon (TIC, 1.39 {+-} 0.03 M) is more than double the concentrations measured in past (2003-2005) samples; (6) The soluble potassium content (measured at 286 {+-} 23 mg/L)more » in the filtrate is in line with all past measurements; and (7) The measured {sup 137}Cs concentration is 7.81E + 08 {+-} 3.9E + 07 dpm/mL of slurry (1.33 {+-} 5% Ci/gallon or 3.18E + 05 {+-} 5% curies of {sup 137}Cs in the tank) in the slurry which is in agreement with the 2005 report of 3.14E + 05 {+-} 1.5% curies of {sup 137}Cs in the tank. The filtrate {sup 137}Cs concentration is 2.57E + 07 {+-} 2.6E + 05 dpm/mL. This result is consistent with previous results. Significant analytical data are summarized in Table 1.« less
