a Comparison of the times t50% required for the dissolution of half of the Fe(III)-precipitate for selected wet and dried precipitates (values from Table 2). b Structural information obtained by Fe K-edge EXAFS spectroscopy on dried precipitates (from Ref. [20]; pcLp poorly-crystalline lepidocrocite; HFO hydrous ferric oxide, Fh-Si silicate-containing ferrihydrite, CaFeP amorphous Ca–Fe(III)-phosphate)
