For instance, in a study, researchers had developed HNT-Fe 3 O 4 nanocomposites
for the adsorption of Methyl Violet 2B (MV2B) from aqueous solutions. Immobilization of magnetic nanoparticles on the surface of HNT imparts a magnetic property
to the nanotube, thereby ensuring its easy separation from solutions. Immobilization
of magnetic nanoparticles does not produce extra contaminants, thus making it suitable for dye removal. The nanoparticles also enhance the surface area and thereby
increase the number of adsorption sites. The developed nanocomposite demonstrated
a maximum adsorption capacity of 20.04 mg/g and showed high reusability when
it retained its properties even after 4 cycles of adsorption–desorption (Bonetto et al.
