Sorbent consisting of nanometre-sized, spherical particles with a magnetic or magnetisable core surrounded by a sorbent shell.
Note: Magnetic nanoparticles have a high surface area-to-volume ratio and a low mass. They are easily dispersed in solution. A magnet facilitates recovery of the nanoparticles from the sample solution or suspension.
