The magnetic disc separator is based on a rotor-stator system (Fig. 4 a). The plexiglass stator disc (30-cm diameter) is equipped with 210 circular neodymium permanent magnets, each producing a 0.6 T magnetic field (Fig. 4 b). The rotor is a plexiglass casing turning around the stator.
Magnetic core–shell microspheres were developed to extract rare earth elements (REEs) from aqueous and brine solutions with up to 99.99% removal efficiency. The shell, composed of a thermally and chemically stable functionalized metal–organic framework (MOF), is grown over a synthesized Fe 3 O 4 magnetic core (magnetite@MOF). The …
The recoveries of spiked plasma and urine samples were in the range of 86.1–115.4%. Results indicate that magnetite micro-solid-phase extraction with gas chromatography and mass spectrometry is a convenient, fast, and economical method for the extraction and determination of amitriptyline and chlorpromazine in biological samples.

V-containing magnetite can occur as either the titanoferrous material or Ti-free magnetite. V-containing titanoferrous magnetite generally has low Ti and Fe contents, …
Abstract The sorption extraction of heavy metal (HM) ions Cu(II), Co(II), and Cd(II) from aqueous media with the use of Zn, Al- and Mg, Al-layered double hydroxides (LDHs) intercalated with citrate and trilonate ions and their composites with magnetic properties, such as Fe3O4/Zn,Al-Cit, Fe3O4/Mg,Al-Cit, and Fe3O4/Zn,Al-EDTA is …
A simple one-step solvothermal method was applied for the preparation of magnetite/reduced graphene oxide (MRGO), and the synthetic nanocomposites with a magnetic particle size of ∼8nm were used as an adsorbent for magnetic solid phase extraction of isocarbophos (ICP) in different sample matrices prior to gas …

Magnetic bead separation can practically be done equipment-free. Here's what happens during the process: 1. Magnetic Beads are Added to the Samples. When the magnetic beads are added to the samples, the DNA will bind to them. The beads have several layers, with the core wrapped by a layer of magnetite.
Under these conditions, about 83.8 ± 0.9% of vanadium was leached from the magnetite ore. XRD pattern of the raw ore. Mineralogical studies of ore thin and polished sections of the sample (Op ...
Magnetite is an iron oxide mineral that is generally black and highly magnetic. The latter property aids in the beneficiation of magnetite ores. Magnetite contains 72.4% Fe by molecular weight, which is higher than hematite, but magnetite ores having lower ore grade (generally 20-30% Fe) owing to the presence of impurities.

The composites based on cobalt–zinc ferrite are as good as the magnetite nanoparticles, and we showed that both of them could be used to purify nucleic acids. ... The extraction showed on row 1 is the commercial phage λ DNA measurement and row 2 is the conventional chloroform DNA extraction. From row number 3 to row number 6, the …
Ferreira used this method to extract microplastics of the 10 most common types of plastic by adding oil to a suspension containing a known concentration of microplastics. The microplastics migrated into the layer of oil. Ferreira then added magnetite powder, which binds itself to the oil and plastic.
Finally, the magnetite nanoparticles were produced using solvent extraction and co-precipitation method. For the solvent extraction, tri-butyl phosphate (TBP) and tri-octyl phosphine oxide (TOPO) was used as an extractant, while 2-ethyl-hexanol, and …
