dc.description.abstract |
The acid-base properties of hydrous ferric oxide were studied by glass electrode potentiometry. From the potentiometric data, surface protonation constants were derived according to the Diffuse Double Layer convention. Chemical equilibrium modelling of the experimental system suggests that titration points below pH 4 should not be used for the determination of protonation constants because of potential HFO dissolution. Surface protonation constant, PZC and binding site estimates agree excellently with currently available best estimates. |

AB - The acid-base properties of hydrous ferric oxide were studied by glass electrode potentiometry. From the potentiometric data, surface protonation constants were derived according to the Diffuse Double Layer convention. Chemical equilibrium modelling of the experimental system suggests that titration points below pH 4 should not be used for the determination of protonation constants because of potential HFO dissolution. Surface protonation constant, PZC and binding site estimates agree excellently with currently available best estimates.
