摘要：

A spectrophotometric determination of thallium (III), based on solvent extraction of an ion-association pair formed between the cationic 2,2'-bipyridyl-iron(II) chelate and the anionic thallium(III) bromide complex is described. The best extractant is 1,2-dichloroethane and extraction is possible over the pH range 2.5-6.7. The composition of the extracted species was confirmed, and conditions were established for the extraction over the concentration range 7.9·10-6-3.5·10-5 M of thallium in aqueous solution. © 1968.
