Studies on Adsorption of Strontium (II) by Expanded Rice Husk

Abstract:

The expanded rice husk, a low-cost and environmental friendly absorbent, was used to remove Sr²⁺ from the simulated radioactive wastewater. The adsorption behaviors for the radionuclide ion Sr²⁺ was studied, and effects of various parameters including pH, temperature, expanded rice husk dose, initial concentration of Sr²⁺ and adsorbed time on the removal rate of ion Sr²⁺ from the simulated radioactive wastewater were evaluated. Results show that Sr²⁺ can be successfully removed from the simulated wastewater by the expanded rice husk, and the removal rate of ion Sr²⁺ on the expanded rice husk achieves as high as 99.37%, which is much higher than that on activated carbon (42.50%) at optimized conditions.
