Figure 3.

A schematic depiction A) shows a possible up‐ and recycling loop: The initial functionalized SPIONs can be reached again regardless of the type of amorphous hydrocarbon. In addition, the collected plastic can serve as a sorbent for liquid hydrocarbons. Successively collecting PE‐MNP and crude oil show superior adsorption capabilities compared to only using functionalized SPIONs due to the accessible porous structure of the PE‐SPION agglomerates B). Columns marked with a star (*) are composed of 2 differently determined extraction values.
