AbstractMagnetic nanoparticles (MNPs) which exhibit magnetic and catalytic bifunctionalities have been widely accepted as one of the most promising nanoagents used in water purification processes. However, due to the magnetic dipole-dipole interaction, MNPs can easily lose their colloidal stability and tend to agglomerate. Thus, it is necessary to enhance their colloidal …

Dry permanent magnetic separators have been widely used in the mineral and coal processing industries due to their simple operation and high separation efficiency. These tools not only discard some amount of bulk gangue from the raw ore, thereby reducing the volume of the grinding operation and cutting energy consumption, but also do not require water in the sorting …

The presence of magnetic inert minerals (RO phase, Fe 3 O 4, Fe) in steel slag powder 13 enables the separation of these minerals from the slag to enhance its gelling properties and facilitate iron resource recovery, thereby improving the activity of steel slag powder. 14 However, during wet magnetic separation operations, hydrated active minerals, such as C 2 S, …

Since the separation of photocatalysts from treated wastewater is essential from the industrial and technical points of view, therefore the separation of F.Z.Perlite from the water was studied with the help of magnets. As indicated in Fig. 10S, F.Z.Perlite can easily be separated due to the magnetic properties of Fe 3 O 4. 3.3. Conclusions

magnetic separation due to the magnetic properties of the seed particles. At first, this process may seem effortful and costly, how ever by choosing the right magnetic seed particles as well as using permanent magnets MSF can be an efficient separation process. Furthermore, due to the strong magnetic force separation matrices

In contrast, no significant agglomeration was detected in the lysis/binding buffer. With regard to magnetic particle recycling, the influence of different storage and drying processes on particle size distribution was investigated. Agglomeration occurred in all process alternatives. For de-agglomeration, ultrasonic treatment was examined.

Magnetic separation has been used in industries to concentrate or remove magnetic minerals/particles for many years. The separation of ultrafine magnetic particles is significantly influenced by aggregation between particles due to various external and interparticle forces, such as gravity, magnetic attraction, van der Waals, electrical double-layer, hydrodynamic, and …

A primary practical challenge is their fine-powdered form, which hinders separation and recycling processes. A promising approach to address these challenges involves integrating magnetic or floating materials into conventional photocatalysts, a strategy gaining traction within the g–C 3 N 4 –based photocatalyst arena. Another emerging ...

Recently, magnetic separation technologies have received attention as an effective method for the capture and removal of nano-scale MPs, combining the beneficial properties of a large active surface area with the capacity for simple and rapid magnetic collection from water, while also being inexpensive and available in large quantities (Piña et al., 2018; Li …

Magnetic seeded filtration (MSF), also referred to as magnetic flocculation (Tsouris et al., 1995) and magnetic adsorption (Franzreb, 2020) is a solid-liquid separation process, which has been used in various applications (Franzreb, 2020). The approach is based on the selective hetero-agglomeration between magnetic seed particles and the ...

As illustrated in Fig. 10 a, it is a two-step process that involves hetero-agglomeration and a high-efficiency magnetic separation. In the initial agglomeration, suspension with MPs and magnetic seeds was added to the device, agitating at a corresponding rotary speed to facilitate the aggregation.

Plastic is a collective term for synthetic or semi-synthetic polymer products and is deeply rooted in today's language.LIFE magazine published an article called "Throwaway living" in the year 1955, in which they euphorically welcomed a new age of the throwaway society that promised dramatic time savings and life improvements through the introduction of single use …

Magnetic separation is a versatile tool for bioseparation tasks. The general concept is the selective binding of a target substance to a magnetizable carrier, whereafter the target substance-carrier-aggregation is magnetically removed from the mixture and can be set free from the magnetic carrier in a suitable buffer [1], [2].This "magnetic fishing" can be directly applied …
