A review of zeta potential measurements using electroacoustics
Shiva Mohammadi-Jam, Kristian E. Waters, Richard Greenwood
Abstract
The electroacoustic technique has been successfully used to determine the zeta potential of concentrated aqueous suspensions for over thirty years. This article reviews its use in mineral processing, ceramics, zeolites, and other industrial minerals and in particular identifies the isoelectric points of these materials, as this parameter is crucial for determining colloidal stability and hence subsequent processing. Some benefits of this technique over the traditional electrokinetic measurement techniques are also highlighted. Finally, the application of the technique to polymer lattices is summarized.
