石墨烯对水中铀的吸附性能研究

Study on Adsorption of Graphene for Uranium in Water

通过吸附实验,探究了石墨烯对水中铀的吸附性能。分别探究了吸附剂使用量,铀溶液初始浓度,初始pH,吸附时间4个因素对吸附率的影响。结果表明,这4个因素对吸附率均有影响。经实验探究找到较适条件,进一步探究吸附效果。在较适条件:吸附剂使用量为50 mg,铀初始浓度为50 mg/kg,pH为6. 3左右,吸附时间在9 h以上时,石墨烯对铀的吸附率为65%。

Through the adsorption experiments, the graphene of uranium in water adsorption effect was studied. The effects of adsorbent usage, initial concentration of uranium solution, initial pH and adsorption time on the adsorption rate were investigated. The results showed that these four factors had an effect on the adsorption rate. Through experimental research, suitable conditions were found and the adsorption effect was further explored. Under more suitable conditions as follows: the amount of adsorbent used was 50 mg, the initial concentration of uranium was 50 mg/kg, the pH was about 6.3, and the adsorption time was above 9 h, the adsorption rate for uranium was 65%.
