Адсорбция глицина на поверхности наночастиц TiO[2] и ZrO[2]

Abstract

Relevance of the work is connected to the need to create aggregation-stable aqueous suspensions of nanoparticles stabilized by surfactants for various applications. In experiment we attempted to use glycine as a stabilizer for plasmachemical ZrO[2] (22.4 м{2}/г) and TiO[2] (8.1 м{2}/г) nanopowders in aqueous suspensions. Adsorption efficiency was measured by the transmittance change on the IR-spectrum of glycine dispersion medium in range 1330.64 cm{-1} (NH[2]-group). It has been shown that the surface of TiO[2] and ZrO[2] nanopowder particles adsorb 6.29% and 5.87% of surfactant substance respectively from the 2M glycine solution for an hour at room temperature.
