摘　　要：在氧化石墨烯(GO)的水溶液中,以乙二胺为还原剂,制备了功能化还原石墨烯(FRG),以其为吸附剂,研究其对水中阴离子型染料活性艳蓝KN-R的吸附性能。利用X射线衍射(XRD)、傅里叶红外光谱(FT-IR)对样品进行了表征;考察了不同的吸附时间、吸附剂用量和溶液pH对吸附效果的影响。结果表明,室温、pH为1、吸附剂投加量为0.5g/L是其最佳吸附条件。在最佳吸附条件下,FRG对活性艳蓝KN-R的去除率可达到95%,说明FRG对活性艳蓝KN-R的吸附效果较好。Functionalized reduced grapheme （FRG） was fabricated from graphene oxide （GO） suspension, using ethylenediamine as the reducing agent. The adsorption performance of FRG on reactive brilliant blue KN-R was investigated. The samples were characterized by X ray diffraction （XRD） and fourier transform infrared spectra （FT-IR）. The effects of adsorption time, pH and adsorbent dosage on adsorption performance were investigated. The results showed that the best adsorption conditions were at room temperature, pH of 1, adsorbent dosage of 0.5 g/L. Under the conditions, the removal rate of reactive brilliant blue KN-R could reach to 95%, indicating that FRG had good adsorption effect on reactive brilliant blue KN-R.
