چکیده

The applications of zerovalent iron nanoparticles in environmental remediation have led to the
development of green methods in their synthesis. This study for the first time reports on the
green synthesis of zerovalent iron nanoparticles using
Thuja orientalis
extract as the reducing
and capping agent at room temperature. The synthesized nanoparticles were characterized with
different techniques such as XRD, ICP/AES, UV-Vis spectroscopy, SEM, and EDX. The reaction
was completed within the first seconds. It was found that phenols and reducing sugars present
in the extract have an important role in the production of nanoparticles. Complete degradation
of methylen blue as a model pollutant was performed using these nanoparticles. Zerovalent iron
nanoparticles showed a strong antibacterial effect on B. subtilis and E. amylovora bacteria. As
a consequence, this green and rapid method can compete with chemical synthesis methods, and
the synthesized nanoparticles can be applied to the degradation of pollutants and bacteria.
