A material comprising positively and negatively charged nanoparticles, wherein one of said nanoparticles contained a magnetically responsive element, are combined with a support molecule, which is a long natural or synthetic molecule or polymer to make a magnetic nanoparticle assembly. When the magnetic nanoparticle assembly is combined with cells, it will magnetize those cells. The magnetized cells can then be washed to remove the magnetic nanoparticle assembly and the magnetized cells manipulated in a magnetic field.

A continuous online process for rejuvenating whole stream of contaminated lean sulfolane in an extraction system is provided. A rejuvenator is installed in the solvent: circulation loop to remove the contaminants continuously to keep the solvent clean, effective and less corrosive. The rejuvenator includes a high pressure vessel with a removable cover and a round rack with vertical stainless steel tubes fitted in the high pressure vessel. A magnetic bar is placed in each stainless steel tube. A screen cylinder is installed outside the ring of stainless steel tubes. As the contaminated sulfolane is passed through the rejuvenator, the rejuvenator picks up contaminants. The rejuvenator can be dissembled to remove the contaminants periodically. The rejuvenator is simple in construction, reliable in operation, and low in operation and maintenance costs. With this rejuvenator, the extraction system operates at high efficiency and high capacity without the dreaded corrosion.

The present invention relates to a magnetic nanoparticle comprising: a) a core containing a ferromagnetic material; b) an outer coating containing a mixture of a lipophilic compound and a hydrophilic compound. The outer coating of the above particle makes the nanoparticle stable in water and, simultaneously, capable of adsorbing/emulsifying large amounts of hydrophobic/lipophilic compounds. The present invention further relates to a process for the preparation of the above- mentioned particles as well as their use in the removal of hydrocarbons from solid or liquid environments and metal ions from contaminated water (wastewater).

The present invention relates to a process for breaking up microplastic/magnetic material aggregates. The process allows both regenerating the magnetic material and obtaining magnetic material-free microplastics. The present invention consists fundamentally of breaking up magnetic material/microplastic aggregates by means of treatment thereof with a concentrated aqueous saline solution, and subsequently separating both types of solids by density and/or by applying a magnetic field.
