Abstract

Abstract Digoxin separation from pharmaceuticals wastes, is small piece of the larger puzzle in holistic risk assessment. In this study, a novel magnetic nano composite (graphene oxide/Fe3O4/SO3H) was synthesized and used as an absorbent for the removal of digoxin from aqueous solution. We utilized UV-Vis spectrophotometry (UV/Vis) for detection and efficient removal of digoxin by magnetic graphene oxide (MGO) in different concentrations. Magnetic absorbent was characterized by thermal gravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The optimized concentration of absorbent and digoxin were 500 and 1 ppm respectively, in which the optimize reaction time was lasting 10 min. Finally, under optimized condition, MGO was used for the efficient separation of digoxin from aqueous solution. GRAPHICAL ABSTRACT
磁性纳米复合材料(Fe3O4-GO-SO3H)作为高级纳米吸附剂对地高辛的高效去除
摘要地高辛从医药废弃物中分离,是整体风险评估中一个比较大的难题。在本研究中,合成了一种新型磁性纳米复合材料(氧化石墨烯/Fe3O4/SO3H),并将其作为吸附剂用于去除水溶液中的地高辛。利用紫外-可见分光光度法(UV/Vis)检测不同浓度磁性氧化石墨烯(MGO)对地高辛的去除效果。采用热重分析(TGA)、傅里叶红外光谱(FTIR)和x射线衍射(XRD)对磁性吸附剂进行了表征。最佳吸附剂浓度为500 ppm,地高辛浓度为1 ppm,最佳反应时间为10 min。最后,在优化条件下,MGO用于地高辛水溶液的高效分离。图形抽象
