J. Sep. Sci. 2017, 40 , 1133–1141 DOI: 10.1002/jssc.201601144 The front cover picture shows ionic liquid (IL) functionalized Fe 3 O 4 magnetic nanoparticles (IL@SiO 2 @Fe 3 O 4 ) that can facilitate the interaction with linear alkylbenzene sulfonates (LAS) via the electrostatic, hydrophobic, and π‐π interactions. Four kinds of LAS (including sodium decylbenzenesulfonate, sodium undecylbenzenesulfonate, sodium dodecylbenzenesulfonate, sodium tridecylbenzenesulfonat) were selected as model compounds to evaluate the applicability of IL@SiO 2 @Fe 3 O 4 for extraction followed by HPLC‐UV analysis. This work proved that the obtained IL@SiO 2 @Fe 3 O 4 is an effective absorbent to extract trace LAS from environmental water samples.
