Abstract
The invention relates to a process for extracting thallium present especially in aqueous wastes of industrial origin. The process, which makes it possible to extract and 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 good selectivity in relation to salts of metals or metalloids which are usually present in industrial aqueous wastes.
