ABSTRACT: Catalytic degradation of organic water pollutants
has emerged as a cost- and energy-effective technique to treat
wastewater. In this work, new silver and magnetite nanoparticles
(NPs) were prepared with a protic poly(ionic liquid) (PIL) based
on a quaternized diethylethanolamine cation combined with 2-
acrylamido-2-methylpropane sulfonate-co-vinylpyrrolidone
(QAMPSA/VP) as a capping and a reducing agent. The
morphology, particle size, surface charge, thermal stability, and
magnetic properties of QAMPS/VP-Ag and Fe3O4 NPs were
investigated to determine the efficiency of the PIL as a reducing
and a capping agent to protect the produced NPs from oxidation or
thermal degradation. The activation energy, enthalpy, and entropy
of the catalytic degradation of the cationic methylene blue (MB)
dye in the presence of QAMPS/VP-Ag and Fe3O4 NPs were determined. The data elucidated that MB was completely degraded in 8
min in the presence of QAMPS/VP-Fe3O4 NPs as a Fenton oxidation catalyst. Moreover, their good magnetic properties allowed
their easy separation and reuse for five cycles without losing their magnetic or catalytic properties
