A new magnetic ionic liquid based salting-out assisted dispersive liquid–liquid microextraction for the determination of parabens in environmental water samples

In this study, a new magnetic ionic liquid (MIL) was designed and prepared, containing a magnetic cation from the ligand N , N -dimethyl biguanide (DMBG) complexing with magnetic center Co 2+ and a bis-trifluoromethanesulfonimide (NTf 2 − ) anion.
