Phytochemical Based Synthetic Approach of Iron Nanoparticles and Their Adsorption Potential for Dye Removal

Iron nanoparticles (Fe-NPs) are mostly synthesized using sodium
borohydride with using aggregation method, which is
a high expensive and environmentally toxic process. Due to
these drawbacks Fe-NPs were synthesized using green methods
based on Haloxylon recurvum plant extract. These synthesized
nanoparticles contains a high concentration of polyphenols
etc. which act as reducing agent. These nanoparticles were then
used for the degradation of congo red dye which is acidic in
nature. The synthesized nanoparticles before and after sorption
of dyes were characterized by a UV-visible, FTIR, SEMEDX,
XRD and specific surface area (BET). Kinetics for the
degradation of congo red dye using these Fe-NPs fitted well to
the pseudo second order reaction. The studies indicated that
Haloxylon recurvum plant iron nanoparticles can be used as
potential adsorbent for the removal of the hazardous dye from
their aqueous solution.
