Studies of the complexation behaviour of transition metals applicable in membrane technologies
… One of these innovative technologies is the Supported Liquid Membrane (SLM) technique. The SLM technology is a membrane-based solvent extraction method that uses a micro-porous hydrophobic membrane as supporting layer. This membrane is impregnated with an organic solvent containing the …

Electrochemically-mediated membrane separations for carbon dioxide capture
… facilitated transport of CO₂ across a planar, supported liquid membrane. A mixture of quinone and dianion adduct is sandwiched between two porous electrodes. An analytical solution for the current-potential equation is derived and then used to quantify the expected performance of the system in …

Development of micro-scale and automated membrane extraction systems for water analysis
… continuous, on-line analysis are also important. Membrane extraction can address both these needs, because it can be carried out in a continuous fashion and can also be miniaturized. This research addresses these two aspects of membrane extraction for the next generation of sample preparation. …
