Агрегативные свойства наночастиц в растворах электролита

Abstract

It has been shown that aggregation of nanoparticles in water suspensions is strongly influenced by. In this work, the we demonstrated strong effect of NaCl concentration (0…50 mM) on the sedimentation and dispersive stability of engineered plasmachemical ZnO nanoparticles. It has been shown that aggregation of nanoparticles in water suspensions is strongly influenced by electrolyte concentration and size of initial powders. The sedimentation and aggregation were estimated, respectively, by changing the the transmittance coefficient change ([delta]Т,%spectrophotometry at 430 nm) and stability by changing the the size of the aggregates in ZnO suspensions (laser diffraction)was evaluated (Ds, nm).
