| Summary: | Заглавие с экрана The focus of the work was to make an attempt to prepare an aggregative-stable suspension of ZnO nanopowder with average particle size of 20-40 nm, which was prepared by plasma method in aminoacetic acid. The infrared spectrums of the solution before and after exposure to nanopowder in 2 M glycine solution was used to check the effectiveness of glycine sorption on the particle surface. It was experimentally revealed that the centrifugate, separated from the nanoparticles after incubation in 2M nanopowder surfactant solution with a particle concentration of 2, 10 and 20 wt.% during a week, had a peak height decrease from 11.1 (initial 2M glycine solution) to 9.45 ... 5.3 ... 4.5 units on the IR spectrum at a wavelength of 1250 cm{-1}, and the percentage of adsorbed glycine 15, 52 and 59.4 %, respectively. Selected surfactant has been efficiently adsorbed on the surface of ZnO particles and can be used to stabilize the nanoparticles in aqueous aggregative-stable suspensions. |
