摘　　要：文章探讨了石墨烯氧化物和铁纳米粒子复合材料去除地下水中钒离子的高效性,研究了不同pH值、接触时间和材料剂量对钒离子去除效率的影响,并确定了最佳的操作条件。结果表明:在pH值为7、接触时间为2.0 h的条件下,该复合材料表现出最高的去除效率;当复合材料的使用量从0.05 g/L增加到0.25 g/L时,吸附效率从42.6%提升到77.2%,虽然吸附效率随材料剂量增加而增加,但当材料剂量在0.1 g/L后继续增加时,吸附效率增幅明显降低;通过SEM、TEM和XRD等技术对其进行表征,发现其具有高比表面积和多孔结构,有利于钒离子的吸附。This article investigates the efficacy of graphene oxide and iron nanoparticle com-posite materials in removing vanadium ions from groundwater.The impact of various pH values,contact times and material dosages on the vanadium ion removal efficiency was examined,and opti-mal operational conditions were determined.The results indicated that the composite material ex-hibited the highest removal efficiency under conditions of a pH value of 7 and a contact time of 2.0 hours;The adsorption efficiency increased from 42.6%to 77.2%as the usage of the composite material rose from 0.05 g/L to 0.25 g/L.Although the adsorption efficiency increased with the mate-rial dosage,the rate of increase significantly decreased when the material dosage continued to rise beyond 0.1 g/L;Characterization through SEM,TEM and XRD techniques revealed that the com-posite material possesses a high specific surface area and a porous structure,which are conducive to the adsorption of vanadium ions.
