Research Interests

Membrane Separation Processes

• Liquid membranes and membrane contactors for selective extraction.

• Development of membranes by incorporation of ionic liquids for application in gas separation and fuel cells.

• Recovery of biohydrogen, dioxins and CO2 capture by supported ionic liquid membranes.

• Fruit juice concentration by osmotic evaporation and membrane distillation in membrane contactors.

• Design of biodegradable films for food applications by inclusion of inert barriers and/or reactive compounds.

•Development of biopolymer membranes for application in pervaporation/nanofiltration processes.
