文摘
- •
Thorium ions were removed from aqueous solutions by modified magnetite nanoparticle.
- •
The effects of process variables on adsorption capacity were investigated by RSM.
- •
Thermodynamic parameters showed that the adsorption was endothermic and spontaneous.
- •
The equilibrium data for the adsorption of Thorium followed the Langmuir isotherm.
- •
The experimental kinetic data were described by the pseudo-second-order equation.
