Line Plot from Scientific Research

PK-edge XANES of the planar Pt/aqueous H3PO3 electrolyte with different concentrations: 0.1 mol dm-3 (0.1 M), 1 mol dm-3 (1 M), and 5 mol dm-3 (5 M). The solid curves represent the average spectra of three measurements at different sample positions, with the shaded regions corresponding to the respective standard deviations of the individual measurements from the mean. A higher spectral weight in the region corresponding to P(+5) compounds is observed for electrolytes with a high content of H2O (i.e., H2O wt %).
