Adsorption of Th⁴⁺ on Waste Beer Yeast

Abstract:

Waste beer yeast was utilized as adsorbent to remove Th⁴⁺ from simulated radioactive wastewater. Effects of various parameters including pH value, temperature, absorbent dosage, and absorption time on adsorption of Th⁴⁺ by waste beer yeast were studied. Beer yeast before and after adsorption was characterized by IR and SEM. The results show that the removal efficiency could be reached 95% at the optimized conditions. The adsorption kinetics was described well by the pseudo second-order equation.
