Fig. 1: Analysis of Hanford tank waste simulants.

A Concentrations of species of interest in five different Hanford tank waste simulants to show trends in composition. The lines in the parallel coordinates diagram are drawn only to guide the eyes. B 53Cr resonance of CrO42− in the five different Hanford tank waste simulants. Spectra correspond to ~1 day of signal averaging. C Integral of 53Cr NMR data in (B) versus Cr(VI) concentration determined by ICP-OES with a linear fit to the integrated 53Cr NMR resonance. Note the units of concentration are millimoles/L (mM).
