中文摘要:
      采用Hummers法合成的氧化石墨烯(GO)与壳聚糖(CTS)来制备复合型吸附剂GO-CTS,通过FTIR和SEM对其结构和微观形貌进行表征。采用吸附法对产物的吸附性能进行研究,考察溶液pH、吸附剂投加量、吸附时间以及铀初始浓度等实验参数对所制吸附剂去铀效果的影响。结果表明,对于10 mg/L的含铀溶液,GO和GO-CTS的最佳吸附条件分别为:pH=4-7、5;投加量1.0 g/L、1.0 g/L;吸附时间为<1 min、70 min,最大去铀率分别为99.5%、97.5%。

英文摘要:
      The composite adsorbent graphene oxide-chitosan (GO-CTS) was prepared successfully and characterized by FTIR spectra and SEM. The products were used to study the adsorption of uranium from aqueous solution. The solution pH, the adsorbent dosage, contact time and initial uranium concentration were investigated to estimate the adsorptive properties. The results show that for the uranium solution with initial concentration of 10 mg/L, the optimum adsorption conditions of GO and GO-CTS were pH of 4-7 and 5; the doses of 1.0 g/L and 1.0 g/L; adsorption balance time of <1 min and 70 min, and the maximum uranium removal rate of 99.5% and 97.5%, respectively.
