High disperse silica in aqueous media
Анотація
An analysis has been carried out of the effects of morphology and surface nature of silica-based fumed oxides on the properties of aqueous dispersions with respect to: particle size distribution, electrophoretic mobility taking into account porosity of aggregates of primary particles, the surface charge density, and adsorption of heavy metal ions from the solution.
