Comparison of particle size measurements of some aqueous suspensions by laser polarimetry and dynamic light scattering

The results of the size distributions measurements of the particles of aqueous suspensions of ZnO, CuO, TiO2, and BaTiO3 by methods of laser polarimetry and dynamic light scattering are considered. These measurements are compared with the results obtained by electron microscopy. It is shown that a laser polarimetry method gives more accurate results for size parameter values more than 1-2.
