Abstract
Described herein are novel emulsion liquid membranes useful for extracting pollutants from industrial wastewater and water. The emulsion liquid membranes include, in various phases, at least one of nanoparticles, an ionic liquid, and combinations of nanoparticles and ionic liquids. Use of the present emulsion liquid membranes enhances the separation and the stability of the ELM method for pollutant extraction and recovery from wastewater and water.
Claims20
An emulsion liquid membrane comprising:
- an emulsion phase comprising an aqueous phase dispersed in an organic membrane phase, wherein the aqueous phase comprises nanoparticles and the organic phase comprises an ionic liquid.
An emulsion liquid membrane comprising:
- an emulsion phase comprising a stripping aqueous phase dispersed in an organic membrane phase, wherein the organic membrane phase comprises an ionic liquid and the stripping aqueous phase comprises a stripping agent and nanoparticles.
A method for removing and/or extracting at least one pollutant, the method comprising:
- dispersing an emulsion phase of an emulsion liquid membrane in an external aqueous phase (W2), wherein the emulsion phase of the emulsion liquid membrane comprises a stripping aqueous phase (W1) dispersed in an organic membrane phase, wherein the stripping aqueous phase comprises nanoparticles and a stripping agent, wherein the organic membrane phase comprises an ionic liquid, and
- removing and/or extracting the at least one pollutant wherein the at least one pollutant is transferred from the external aqueous phase (W2) through the organic membrane phase to the stripping aqueous phase (W1) and the at least one pollutant reacts with the stripping agent in the stripping aqueous phase (W1) and is removed from the external aqueous phase (W2).
