The experiments were carried out in a custom 3D-printed cell which consists of an aqueous compartment containing 0.1M KOH pre-equilibrated with CO2 (pH=7.8) and an organic liquid compartment containing a mixture of 1.2M of KOH in EG. For the MAMG experiment with the mixture of IL with EG, the organic liquid was prepared additionally with the relevant IL mol fraction (at which the maximum ionic conductivity was observed). Solutions in both compartments were continuously recirculated with a Cole Parmer MasterFlex multi-drive peristaltic pump. An anion exchange membrane from SnowPure (Excellion A200, pretreated with water at 80 o C) was sandwiched to separate the aqueous and organic compartments. Migration in the MAMG process was enabled by using Cu mesh (4cm 2 , American Elements 99.99% pure) as cathode and using Carbon Toray paper (4cm 2 , Fuel Cell Store, 190um Toray 060) as anode placed in organic and aqueous compartments. A DC source from Eventek at constant current mode facilitated the migration of ions from the organic side to the aqueous side. During the MAMG experiment, a simulated flue gas of 90% N2 and 10% CO2 was continuously bubbled in the organic liquid. The migration flux of the dissolved CO2 was continuously monitored as a function of the pH decrease in the aqueous side by a Thermo Orion A111 pH probe. A schematic diagram of the electrochemical setup for MAMG process is available in our already-published article.
