As the dialytic tubing is impermeable for big molecules of receptor, the anions crossing the barrier of dialytic tubing to form complex with the receptor stay entrapped inside and can be removed from the solution. NMR methods were used to study the complexation properties of given receptors as well as to determine the concentration changes during dialytic experiments.

Membrane processes are not commonly used in enantiomer separation due to insufficiency explication of separation mechanisms and because the results of chiral membrane separation are not quite satisfying, especially in comparison with other separation technics, namely HPLC. A new method for selective separation of enantiomers by membrane processes taking advantage of ionic liquids is present. The supported chiral room temperature ionic liquid membrane is used for separation of enantiomers. Volatile enantiomers are separated by pervaporation and non-volatile enantiomers by pertraction.
