A single-step magnetic separation procedure that can remove both organic pollutants and arsenic from contaminated water is clearly a desirable goal. Here we show that water dispersible magnetite nanoparticles prepared by anchoring carboxymethyl-β-cyclodextrin (CMCD) cavities to the surface of magnetic nanopa

Immunomagnetic particles, i.e. magnetic particles with immobilised specific antibodies against the target structures, have been used for the isolation of various antigens, both molecules and cells [ 5] and can thus be used for the separation of specific proteins. Magnetic separation procedures can be employed in several ways.

Owing to the non-homogeneity of the magnetic field throughout the magnetic particle solution, magnetophoretic motion is initiated in which the magnetic particles migrate towards the region where the magnetic field gradient is the highest (figure 3 b) . In such a way, magnetic particles are removed from the suspending medium and …

3.4.3 Magnetic separation. Magnetic separation method has been widely used in pre-treatment process of e-wastes. The crushed particles of e-wastes often contain a relatively larger content of iron and nickel than other metals. These metals possess magnetic properties that can be used for their effective separation from the rest of the materials.

Magnetic separation is the process of separating components of mixtures by using a magnet to attract magnetic substances. The process that is used for magnetic separation separates non-magnetic substances from those which are magnetic. This technique is useful for the select few minerals which are ferromagnetic (iron-, nickel-, and …
