Figure 6

Dissolution of goethite particles vs time. The fraction of solid dissolved, a, was calculated from [Q] using the Q:Fe(II) stoichiometry. Experiments were performed in triplicate, and all data points are shown. Model curves for 2D diffusion kinetics were calculated by minimizing the unsigned mean error between the experimental data and the model. The solid curve is the best fit for the nanorod data, and the dashed for the microrod data.
