Zusammenfassung:	Process for the extraction of the thallium present especially in aqueous effluents of industrial origin. The process, which makes it possible to extract and to recover thallium from a solution which contains it in the form of a salt of a strong inorganic acid comprises a stage of bringing the said solution into contact with an ion exchange resin containing a thiol group. This process exhibits a good selectivity in relation to the salts of metals or metalloids usually present in industrial aqueous effluents.
