Abstract
The triethylene-tetramine modified magnetic chitosan sorbents (TETA-MCS) were synthesized for the adsorption of Th(IV) ions from aqueous solution. FTIR analysis indicated that the amine and hydroxyl groups of TETA-MCS were involved in the adsorption process for the formation of O, N–Th(IV) complex. Th(IV) adsorption was pH dependent and the maximum adsorption was observed at pH 4.0. The adsorption kinetic data could be interpreted by pseudo-second-order kinetic model. The equilibrium data were correlated with the Langmuir, Freundlich and Temkin models, and the maximum monolayer adsorption capacity obtained from the Langmuir model was 133.3 mg Th(IV)/g at 25 °C. Thermodynamic parameters revealed the feasibility, spontaneity and endothermic nature of adsorption. The sorbents were successfully regenerated using 0.2 M HNO3−0.1 M EDTA and exhibited good reusability.
