dc.description.abstract | The impact of a varying rotating magnetic field in stimulating adsorption of fluoride ions onto a polypyrrole
magnetic nanocomposite synthesized via in situ a polymerization process was evaluated. Under the effect
of a rotating magnetic field, improved removal of adsorbate (10 mg L 1
) from aqueous solution using the
polypyrrole magnetic nanocomposite was observed, with a maximum removal of 78.2% observed at
a magnetic field intensity of 0.019 T. Particle aggregation resulting from the force owing to the gradient
on the particles as the magnetic field was increased resulted in improved fluoride removal. This
aggregation of particles leads to an improved chain collision and expanse of particle interaction with the
fluoride solution. The process of adsorption of fluoride by the PPy/Fe3O4 nanocomposite followed both
the Freudlich isotherm and the Temkin isotherm. Interestingly, under the effect of the rotating magnetic
field, the adsorption process was best described by the Freundlich isotherm | en_US |
