Abstract

Bulk liquid membranes (BLMs) are so far an important research subject in the field of separation processes of target components from a chemical mixture. Both flexibility of the BLM configurations as separation tools along with using very expensive selective extractants as carriers without the risk of being wasted during processing render superior separation ability. The current paper aims to provide useful, up-to-date information about the common types of BLM devices. An attempt has been made to classify most of the tested BLM configurations with a sufficient description of the relevant technical aspects. Moreover, the different applications of BLM configurations are thoroughly discussed and evaluated describing advantages and drawbacks. Non-dispersive BLMs are only useful for laboratory-scale separation purposes as a preparation step of diluted analytical samples to separate and enrich the analyte. They can also serve as available and easy experimental methods in the laboratory to investigate the transport and extraction properties of new extraction systems. Based on the literature, the emulsion BLMs are likely to be more suitable for use in larger-scale applications on the pilot or plant level due to their larger contact surfaces and faster mass transfer.
