摘要:
A fundamental investigation on the removal of uranium from aqueous solutions by wheat straw was conducted in batch conditions. The influence of different experimental parameters such as modified methods, pH, contact time, adsorbent dose, initial concentration, and temperature, on the kinetics of uranium removal was studied. The results showed that the higher adsorption rate of uranium on wheat straw was modified by NaOH. At 303 K and pH was 3.0, the saturation adsorption was up to 1.20 mg/g at approximately 120 min. The uranium uptake was quant...
