Kinetic, Equilibrium and thermodynamic studies thallium adsorption from aqueous solutions by activated carbon modified with rhodamine B

Thallium (Tl) was accidentally discovered by William Crookes in 1861 by burning the dustfrom a sulfuric acid industrial plant [1]. It occurs primarily in association with base metal andprecious metal bearing sulfides [2]. Tl is a highly volatile and toxic heavy metal regarded tocause pollution even at very low concentrations of several parts per million. Despite theextremely high risk of Tl in the environment, limited information on removal/recovery exists.This work focussed on the use of activated carbon modified with Rhodamine B to determinethe sorption potential and recovery of Tl.
