The solvent extraction of some thallium(I) chelates

Studies of the extraction of thallium (I) from aqueous solution into an immiscible organic solvent have been made using 71 chelating reagent-solvent pairs involving 16 reagents and 17 solvents. The data have been analyzed to identify the predominant species involved, and association and partition constants have been estimated in many cases, The best extraction systems seem to be those involving 3phenylpropylxanthate and chloroform, chlorobenzene or methylene chloride.
