Determination of an average rate constant for the rapid coagulation of polydisperse suspensions using photon correlation spectroscopy
Abstract
The rapid aggregation of various polydisperse mixtures of polystyrene latices and one titanium dioxide suspension has been investigated using a photon-correlation technique. A method has been developed that gives reasonable values for the Smoluchowski rate constant of polydisperse suspensions without precise knowledge of their particle-size distribution.
