Microfluidic devices as gas – Ionic liquid membrane contactors for CO 2 removal from anaesthesia gases
Abstract(#br)This work proposes a microfluidic gas – ionic liquid contactor for CO 2 removal from anaesthesia gas, containing Xe. The working principle involves the transport of CO 2 through a polymer flat membrane followed by its capture and enzymatic bioconversion in the ionic liquid solvent. Microfluidic devices enable a rapid and inexpensive screening of potential CO 2 absorbers. The alveolar – type design of the ionic liquid chamber was adopted to reduce mass transfer limitations of CO 2 through the liquid phase.
