Coolside waste management research. Annual technical progress report, October 1991--September 1992
Sample collection - soils, base sand, and conventional fly ash for loading the field lysimeter calls were selected and either obtained or in process of being delivered. Chemical and Mineralogical Characterization of the Waste - This activity is proceeding with proximate and ultimate analysis of the materials being completed. In addition the major and minor element analysis was performed by several analytical techniques. The protocol for rapid, thick-target proton induced x-ray emission (PIXE) and proton induced gamma emission (PIGE) spectroscopy were developed. Analysis of 97 Coolside waste samples from Run 3 and 77 samples from Run 1 showed a wide range of concentration values were observed for most of the values. In Run 3 calcium content increased with time and titanium content decreased. Likewise, a change in sodium content occurred with average concentrations being 1.26 {plus_minus} 0.03 wt% during the first half of the run while it dropped to 1.18 {plus_minus} 0.03 wt% in the latter part of the run. Vanadium and bromine directly correlate with the calcium content indicating these elements are either introduced in the hydrated lime or their capture efficiency depends on the calcium concentration in the waste. The other elements whose concentrations increase with time are zinc, germanium, arsenic, gallium and lead but do not appear to be introduced with the lime or have capture efficiencies that are affected by the calcium content in the ash.
