- Abstract
The new sorbent—sugercane stalks on the adsorption of uranium-containing wastewater was studied by static adsorption experiments in this research. Its feasibility and adsorption capacity as a biological adsorbent was verified through modification experiments. The influence of adsorbents dosage, adsorption time and temperature, adsorption solution pH, initial concentration on the adsorption of uranium after the modification was studied and the adsorption mechanism of uranium adsorption by sugarcane stalks was discussed. The experimental results showed that adsorption efficiency increased about 50% after modification by ZnCl2 and NaOH, and the maximum adsorption efficiency was 86.6% and the maximum adsorption capacity was 2.5 mg/g at 303 k, pH = 3, the time was ahout 90 mins, modification was feasible. Warming was conductive to the adsorption. The amount of adsorbent to the optimum volume of the solution was 8 g/L. The results indicated that sugarcane stalks can be used as the good uranium-containing wastewater decontamination biosorbent.
