Abstract
The influence of dispersant, pH and various additives on stability of ZnO suspension have been studied. Water and ethylene glycol were used as dispersants, sodium dodecyl sulfate (SDS), cetyltrimethylammonium bromide (CTAB) and sodium carboxymethyl cellulose (NaCMC) have been adsorbed on ZnO particles. Equilibrium in the system is mostly influenced by pH. The lowest stability of suspensions of ZnO was found around isoelectric point which was confirmed by simultaneous measurement of particle size and zeta potential. The values of the zeta potential were also affected by the presence of surfactants, especially SDS and CTAB.
