[Display omitted] •TNTs show large adsorption capacities for both Tl(I) and Tl(III).•Ion-exchange between Tl+ and Na+ is the primary mechanism for Tl(I) adsorption.•Ion-exchange plays the main role in adsorption at low Tl(III) concentration.•Co-precipitation of Tl(OH)3 and TNTs is dominant at high T...
