【 摘 要 】

Three dip samples of suspended sludge slurry were obtained from Tank 51H in December, 2003 after addition of corrosion control chemicals to the tank. The samples were sent to the Savannah River Technology Center for analysis. The analyses requested included those required for Extended Sludge Processing washing controls and corrosion controls. The washing controls require the measurement of the sodium concentration, density, and weight per cent solids of the sample. The corrosion control analyses require determination of the nitrate, nitrite, and free hydroxide concentrations in the supernate. The low per cent relative standard deviations for all analytical results indicate good analytical precision for the three replicates. The blanks submitted with the sample show no contamination of the samples from reagents used in the sample preparations. The results of the density and weight per cent solids measurements appear consistent with the sodium concentration measured in the supernate.
