Abstract Thallium (Tl), an extremely toxic heavy metal, has received much less attention than other toxic heavy metals such as Hg, Cd, and Pb. To date, Tl pollution control studies have usually focused on its removal only, while very few studies have explored its recovery from wastewater. In this study, a magnetite (Fe3O4)-mediated reversible adsorption-desorption process for the removal and recovery of Tl(I) from wastewater was investigated. Fast and efficient removal of Tl(I) was achieved via adsorption under alkaline conditions at pH > 11.0, while rapid and effective enrichment of Tl(I) was achieved via desorption under acidic conditions at pH
