Abstract :

[en] Coalescence is strongly affected by trace components. Studies suggest to use the DLVO force in coalescence modelling. Data regarding the electrostatic potential are thus needed. Determination of the partition coefficient of a charged dye dissolved in salt-containing two-phases systems allows to evaluate the electrostatic potential difference relative to a reference system by evaluation with the extended Albertsson model. The corresponding first settling tests show the strong effect of the relative electrostatic potential difference on the dispersion behavior.
