From: Reductive dissolution of As(V)-bearing Fe(III)-precipitates formed by Fe(II) oxidation in aqueous solutions

Fig. 1

a, b Dissolved Fe(II) over the course of reductive precipitate dissolution for a wet and b dried precipitates formed by Fe(II) oxidation at (P/Fe)init ratios from 0 (Ca-00-00) to 1.5 (Ca-15-00) in Ca electrolyte. Thin lines serve to guide the eye. c, d Corresponding plots of ln(1-Fe(II)/Fetot), the natural logarithm of the residual Fe(III) fraction, versus time for c wet and d dried precipitates. Solid lines were calculated with kapp derived from the linear regression of the experimental data (Table 2)
