Ferrocene based redox-active compounds have a total number of cyclopentadienyl substituents that is three or greater per ferrocene core. The cyclopentadienyl substituents generally have a linker and a solubilizing group. An aqueous solution of the redox-active compound and a salt may be used as an electrolyte. Aqueous compositions including the redox-active compounds may be used in electrodialysis systems.

Disclosed is a method for degrading antibiotics by aqueous phase transfer catalysis using an anionic liquid and hydrogen peroxide, including: adding hydrogen peroxide to a wastewater containing the antibiotics to obtain a first mixture, and adjusting a pH of the first mixture to 3-4 to form an aqueous phase, and adding a catalyst to a water-insoluble ionic liquid to obtain a second mixture, and stirring the second mixture to form an ionic liquid phase, wherein the catalyst is selected from the group consisting of ferrocene, iron dodecyl sulfonate, ferrous dodecyl sulfonate, and copper dodecyl sulfonate; and mixing the aqueous phase and the ionic liquid phase in a volume ratio of (8-11):1 to obtain a mixed phase, and stirring the mixed phase to degrade the antibiotics.
