Description

An Efficient Nanomaterial Centrifugal Separation Equipment

technical field

The invention relates to a separation device, in particular to an efficient centrifugal separation device for nanomaterials.

Background technique

Magnetic nanomaterials (such as magnetic carbon nanotubes, magnetic graphene, etc.), as a new type of adsorption material, have rapidly become a hot research topic due to their unique physical and chemical properties. Due to its advantages of large specific surface area, large adsorption capacity, some surface functional groups and hydrophobic surface, it can strongly adsorb certain heavy metal ions and organic compounds. In recent years, researchers have either directly used magnetic nanomaterials as adsorbents or as carriers to study Its adsorption, separation and purification of organic and inorganic substances in wastewater.
