6Synthesizing and characterizing the magnetic EDTA/chitosan/CeZnO nanocomposite for simultaneous treating of chromium and phenol in an aqueous solution显示文摘A new magnetic nanocomposite chitosan/EDTA/CeZnO(MEC-CeZnO)is synthesized as an efficient and eco-friendly bio-compound for the removal of chromium Cr(VI)metal ions and phenol organic matters from aqueous solutions.Nanocomposites are characterized using field emission scanning electron microscope,energy dispersive X-ray spectroscopy,transmission electron microscope,X-ray diffraction,X-ray photoelectron spectroscopy,Fourier transform infrared spectroscopy,diffuse reflection spectroscopy,and PL methods.The reduction rate of Cr(VI)ions and phenol degradation is evaluated under various experimental conditions,separately and simultaneously.The average pore diameter and specific surface of MEC-CeZnO nanocomposite are obtained 50 nm and 210 m^(2)·g^(-1)respectively,which suggest the successful synthesis of the nanocomposite because of the increased surface area and reduced pores in comparison to previous studies.Moreover,the best Cr(VI)and phenol reduction efficiencies are 98%and 92%at 180 min of retention time,both following the Langmuir-Hinshelwood first-order kinetics.The mechanisms of Cr(VI)and phenol removal from aqueous solutions involved Cr(VI)reduction,phenol oxidation,and adsorption.Examining the reusability of MEC-CeZnO showed that both degradation and recovery capacity is stable in 5 cycles.Masoumeh Sheikh Hosseini Lori Mohammad Delnavaz Hoda Khoshvaght 2023Chinese Journal of Chemical Engineering2023,58,6:0
7Photodegradation of reactive blue 19 dye using magnetic nanophotocatalyst α-Fe_(2)O_(3)/WO_(3):A comparison study of α-Fe_(2)O_(3)/WO_(3)and WO_(3)/NaOH显示文摘The photocatalytic degradation of reactive blue 19(RB19)dye was investigated in a slurry system using ultraviolet(UV)and light-emitting diode(LED)lamps as light sources and using magnetic tungsten trioxide nanophotocatalysts(α-Fe_(2)O_(3)/WO_(3)and WO_(3)/NaOH)as photocatalysts.The effects of different parameters including irradiation time,initial concentration of RB19,nanophotocatalyst dosage,and pH were examined.The magnetic nanophotocatalysts were also characterized with different methods including scanning electron microscopy(SEM),energy-dispersive X-ray spectroscopy(EDS),transmission electron microscopy(TEM),X-ray diffraction(XRD),photoluminescence(PL),differen-tial reflectance spectroscopy(DRS),Fourier transform infrared spectroscopy(FTIR),and vibrating sample magnetometry(VSM).The XRD and FTIR analyses confirmed the presence of tungsten trioxide on the iron oxide nanoparticles.The VSM analysis confirmed the magnetic ability of the new synthesized nanophotocatalyst α-Fe_(2)O_(3)/WO_(3)with 39.6 emu/g of saturation magnetization.The reactor performance showed consid-erable improvement in the α-Fe_(2)O_(3)-modified nanophotocatalyst.The impact of visible light was specifically investigated,and it was compared with UV-C light under the same experimental conditions.The reusability of the magnetic nanophotocatalyst α-Fe_(2)O_(3)/WO_(3)was tested during six cycles,and the magnetic materials showed an excellent removal efficiency after six cycles,with just a 7%decline.Mohammad Delnavaz Javad Farahbakhsh Seyed Sajad Mahdian 2021Water Science and Engineering2021,14,2:0
