dif erent metal ions using dif erent nanoparticles.
Removal of heavy metal
ions and micropollutants from aqueous streams using nanoparticles con-
tinues to be extensively researched. h e focus is primarily on modii cations
to improve the detection ei ciency and the nanoparticle stability.
h e growing use of engineered nanoparticles and nanomaterials for
water purii cation has raised concerns for human exposure. h is stems
from the absence of specii c technologies aimed at the removal of engi-
neered nanomaterials from the water (see Figure 10.3) and the safety of
the new nanoparticles and nanomaterials that may be used by the water
industry.
10.4 Core Material/Nanoi llers
Silica is ot en used as a core material for the fabrication of core-shell
nanocomposite materials due to its unique properties. Spherical silica
particles, with diameters ranging from 5 nm to a few microns, suitable
for use in the synthesis of core-shell nanostructures, can be prepared
by using various methods. A very popular route for the synthesis of
silica particles is the Stöber method. h is method allows the synthesis
of spherical and homogenous silica particles of desired size without the
