| Riassunto: | Title screen The study of biological activity of manufactured nanopowders lacks experimental data concerning the influence of electrolyte nature and content on the degree of nanoparticles aggregation in aqueous suspensions. Using the dynamic light scattering technique, it has been shown how the ionic strength (0.0001…100 mM) of mono- and bivalent electrolyte (Na+, Ca2+) solutions influences the size and zeta-potential of Al (90 nm) and Al2O3 (30 nm) nanoparticles. It has been determined that the aggregative effect of counterions decreases when their charge increases. The weaker influence of Ca2+ concentration on the aggregation of both nanoparticles has been demonstrated. For Al2O3 nanoparticles, the stronger influence of Na+ concentration on the size and charge of aggregates has been observed. Режим доступа: по договору с организацией-держателем ресурса |
