✦ Synopsis

The formation of silica shells on core silver particles by a modified St öber process was investigated and the coated particles were characterized using UV-visible spectroscopy, transmission electron microscopy, and electrophoresis. The deposition conditions, such as reagent concentrations and reaction time, were optimized in order to obtain uniform surface layers of silica and to avoid excess precipitation of the latter.

The adsorption of several anionic dyes on nanosize alumina-modified silica particles of different compositions and modal sizes has been studied. These silica cores have the same surface properties as alumina dispersed in aqueous solutions. The negatively charged dyes are electrostatically attracted
