Liquid Membrane Technology for Sustainable Separations

Green supported liquid membranes: The permeability activity-based linear operation (PABLO) method

“…12 systems (1 solute × 4 green-SLM × 3 stripping phase) have been measured. To fit equation (8) to each experimental k dataset of j datapoint number, both feed and stripping solute affinities must be corrected from COSMO-RS predictions. In total, there are three parameters to be fitted: γ Water i , γ 0.1MNaOH i , and γ 0.5MNaOH i .…”

“…Liquid Membrane (LM) technology has been presented as an innovative approach for the selective extraction of diluted species from liquid or gaseous matrices, including the recovery of biomolecules, amino acids, metal ions, and rare earths, as well as the treatment of wastewater, nuclear waste, and removal of heavy metals [8]. By including an immiscible solvent within the porosity of an inert thin substrate in the so-called supported liquid membranes (SLM), allows to reduce the extraction media requirement and thereby the mass transfer resistance [9].…”
