- Abstract:
- Prediction of the solubility of ferric iron in freshwaters is a long-standing challenge in aquatic chemistry. Recent progress in the modelling of cation binding by natural organic matter has led to a theoretical basis for calculating concentrations of truly-dissolved Fe(III), i.e. the sum of inorganic solution species plus dissolved organic complexes. We are now able to test the hypothesis that the activity of Fe3+ is governed by the dissolution-precipitation reactions of (colloidal) iron oxides, ubiquitous components of freshwaters. This will be done by using ultrafiltration to estimate concentrations of truly-soluble Fe(III) in a range of freshwaters, and by performing speciation calculations with WHAM6, a speciation code incorporating a comprehensive model of metal-organic interactions.
