The present invention comprises a supported liquid membrane carrier liquid with a dielectric constant between approximately 20 and 32, more particularly between 22 and 28, and preferably about 24, and the use of that carrier liquid in a supported liquid membrane device to extract one or more chemical species from a feed liquid. The invention further comprises such a device where a temperature gradient is maintained between any of the feed, carrier, or strip liquids. In another embodiment of the invention, any of the feed, carrier, or strip liquids are conditioned, for example, by passing the liquids through a purifier, or replacing lost carrier liquid. In another embodiment of the invention, two or more devices are connected in series or parallel.
