Abstract The aggregation kinetics and cluster morphology of polystyrene particles in rapid colloidal aggregation are studied. Experimental results for three aggregating systems with different amount of surfactant adsorbed on the particles are presented. The homogeneity parameterλ of the Van Dongen model was determined from the time evolution of the mean hydrodynamic radius, measured by dynamic light scattering. This parameter allowed the aggregation mechanism to be identified. The cluster fractal dimension was measured by static light scattering.
