| 要約: | Заглавие с экрана The development of stable suspensions of nanoparticles is an urgent task for creation of bactericidal sols, biological supplements, paint coatings etc. The influence of low molecular anionic surfactants on the sedimentation stability of aqueous dispersions of TiO[2], ZnO plasmochemical nanopowder is demonstrated in this work. It is shown that the electrokinetic properties of the nanoparticles depends on the concentration and type of ionic surfactant. The carboxyl groups of citric and acetic acids were used as surfactants. Using the method of dynamic light scattering it was shown that the adsorption proceeds less intensively in the sodium acetate suspensions than in sodium citrate. |
