The interaction of colloidal carboxylated latex particles with a packed bed of glass beads is studied by means of chromatographic techniques. For these negatively charged surfaces we find strong evidence of particle attachment as well as detachment processes. In particular, the rate constants of the two processes are measured from the particle breakthrough curve of a pulse input. Ionic strength is...
The aggregation of colloidal polystyrene latex particles has been investigated using small-angle static light scattering. Aggregate structures were found to be mass fractal in nature for both the salt-aggregated and depletion-flocculated systems. The measured fractal dimensions were found to be highly dependent on the salt concentration, the concentration of non-adsorbing polymer and the initial particle...
Dilute aqueous dispersions of colloidal polystyrene latex spheres were flocculated by adding a nonadsorbing polymer sample, poly(acrylic acid). The structural compactness of the flocs thus formed was characterized in terms of their mass fractal dimension using the small-angle static light scattering technique. It was found that with low poly(acrylic acid) concentrations and thus weak depletion attraction...
