Current research unites the efforts of the scientists in the
synthesis of tailored functionalized silica-based materials,
physicochemical characterization of their surface binding
properties with valuable experience of their implementation in
ecology and nanomedicine. The proposed report is set up to
mobilize synergy effects within development of silica materials
with predetermined characteristics for successful solution of
problems associatedwithwater and soil remediation and public
health. The purpose of the present research is to develop smart
functional silica materials for water purification (from organic
and inorganic pollutants). The specific choice of silica materials
is explained by their structural rigidity, mechanical and thermal
stabilities (provided by inorganic component) in addition to
specificity and selectivity (attributed to organic component).
Moreover, the usage of one-pot synthesis makes it possible
to regulate the porosity and the nature of the surface layer of
such materials to meet the requirements of each application.
We used several approaches to regulate the sorptive capacity
of materials produced during the synthesis: Regulation of
matrix porosity, variation in the functional groups content,
incorporation of extra groups with different properties. It was
shown that the changes in the synthesis temperature can affect
themorphology and zeta-potential of theobtainedparticles, the
content of groups, and the adsorption properties. We studied
the adsorption properties of the functionalized silica spheres
in relation to copper (II) ions and organic dyes from aqueous
solutions.Furthermore,antimicrobialperformanceoftheamine-
containing materials that were synthesized was also analysed.
