Various hydrocarbons are efficiently extracted from water by using a new
sorbent material based on covalently functionalized magnetic
nanoparticles. The functionalization of the magnetite nanoparticles with
a self‐assembled monolayer of hexadecylphosphonic acid renders the
nanoparticles oleophilic and the magnetic nature of magnetite allows for
simple extraction of the hydrocarbon‐soaked sorbent. The sorbent
material is capable of extracting single contaminants such as alkanes
and aromatics and complex hydrocarbon mixtures such as crude oils in
high extraction rates of up to 14 times the sorbent volume. Experimental
results are explained by molecular dynamics simulations on the
adsorption of single components from a hydrocarbon‐water mixture to the
alkylphosphonic acid layer on the nanoparticles. The core–shell sorbent
material is highly stable and therefore, reusable over several
successive extraction cycles without degradation. The extraction
performance is determined at different water temperatures, different
water sources, and different magnetic core materials and evaluated
compared to heptadecanoic acid functionalized magnetite. The new sorbent
material provides the opportunity for an efficient, reliable,
inexpensive, and environmental friendly removal of hydrocarbons from
