چکیده
The growing issue of water scarcity, exacerbated by climate change and extended
droughts, underscores the critical need for effective water and was tewater treatment
s trategies. In this s tudy, NiFe2O4 magnetic nanoparticles were synthesized using a
green synthesis approach in peppermint (Mentha) extract medium, ensuring an ecofriendly
fabrication process. The magnetic nanoparticles were coated and modified
with chitosan, resulting in a new nanocomposite with improved adsorption properties.
This green-synthesized magnetic chitosan nanocomposite was characterized using
FTIR, XRD, VSM, SEM, and TEM, and subsequently applied to remove cyanide
from contaminated groundwater and indus trial was tewater. The adsorption process
was optimized through an experimental design procedure, achieving a maximum
removal efficiency of 97.1 ± 3.8% at a 95% confidence level, closely matching
the experimental results of 95.8 ± 7.7%. The results highlight the potential of this
sus tainable nanocomposite for water and was tewater treatment, aiding effective water
resource management in the face of climate change and growing water scarcity.
