The dynamic mobility of CaCO_3 suspensions in the presence of polyelectrolyte as a dispersing agent was measured with varying volume fraction of particles, and it was converted to zeta potential and size distribution by theoretical treatment of dynamic mobility spectra. The results of the suspension that the particles have cationic, anionic and nearly neutral charge by adsorption of polyelectrolytes fitted to the theoretical calculation derived by O'Brien. For the suspension stabilized by steric hindrance, the zeta potential and size distribution calculated y dynamic mobility spectra can be obtained up to 0.6 of volume fraction.
