Abstract
This work has been carried out to synthesize, characterize and use the following:
1- A newly amine-functionalized silica-pectin hybrid material (P-AFS)
was prepared by a hard template method via grafting of the silica
precursors, covalently bonded to pectin in the presence of toluene for
efficient phosphate removal .The adsorbent properties were
investigated, and the phosphate adsorption properties and processes
on P-AFS were examined and compared to the adsorption of various
anions.
2- Lanthanum hydroxide La (OH)3 nanorod employing a facile method
via a co-precipitation method using NaOH as an auxiliary agent. The
formation of nano La (OH)3 rod was confirmed by transmutation
electron microscopy (TEM), X-ray diffraction (XRD), and Fourier
Transform Infrared Spectroscopy (FTIR).Phosphate
3- Green zero-valent iron (G-nZVI) and graphene nano- zero-valent iron
(Gr-nZVI) as possible alternative methods for its removal from
aqueous solutions. The adsorbents were successfully synthesized by
the green approach, and different investigation techniques were used
for determination of their characteristics. The conditions and the
mechanism of adsorption of nitrate on G-nZVI and Gr-nZVI were
studied in detail. For this study that includes: Reduction of Nitrate by
graphene nanoscale Zero-valent Iron.
