Abstract

See full text

Disclosed are methods of separating solute from solvent using a photoactive extractant. The photoactive extractant can be switched between two states by exposure to light. This can change the affinity of the photoactive extractant for either the solute or the solvent, causing absorption of the solute or solvent. The photoactive extractant can then be separated from the fluid stream containing the solute or solvent. The absorbed solute or solvent is then separated from the photoactive extractant. The photoactive extractant is a photoisomer. Applications for these methods include desalination, water purification, and metal extraction.
