Figure 5
Fe K-edge energy (E0) values, shown as square points, as a function of time to 100 s, measured from a 0.69 M Fe(II)Cl2 aqueous solution sample at 573 K. The average error in E0 is ±0.08 eV, as determined from Lorentzian peak fitting. The solid line is the fit to the data using a second-order exponential decay function [equation (1)[link]]. The inset shows a natural log plot of the quantity (E0 − E0b), where E0b is an estimated edge energy value of 7122.7 eV at t = 0, clearly exhibiting two distinct linear slopes indicative of two separate kinetic processes. The straight lines are guides to the eye only.
