| Summary: | Заглавие с экрана Applications of industrial nanopowders are limited by the lack of information about their adsorption properties in aqueous solutions of surfactants. The adsorption coefficient of aminoacetic acids in aqueous suspensions of nanosized (40 nm) and microsized (200 nm) ZnO particles was determined in the research. It has been experimentally shown that the coefficient of surfactant adsorption depends on the aging time, the nature of the surfactant and the size of the particles being studied. An increase of the adsorption coefficient is characteristic for all particles through the series "glutamic acid-lysine-glycine". As the specific surface area of plasma-chemical particles increases, the adsorption coefficient decreases: at 60-min exposure in the "Glut-Lys-Gly" series, the Ads coefficient is "0,3‒0,7‒1,5 mM/m2" and "0,9‒2, 6‒7,5 mM/m2 for ZnO-40 and ZnO-200, respectively. Non-ionic glycine is most efficiently adsorbed and more easily retained by the surface of highly dispersed zinc oxide particles. |
