We removed Cr VI (in the form of HCRO4- and CrO4--) from an aqueous solution. This removal was carried out using magnetite nanoparticles functionalized with a cationic surfactant, CTAB. My question is as follows: are the X-ray spectra of the nanoparticles before and after extraction different?Thank you to everyone for your contributions
Yes, the X-ray spectrum can potentially change after the electrostatic adsorption of Cr(VI) onto magnetite nanoparticles. This change can be observed in X-ray spectroscopy techniques such as X-ray photoelectron spectroscopy (XPS) or X-ray absorption spectroscopy (XAS).
If Cr(VI) ions adsorb onto the surface of magnetite nanoparticles, they can interact with the surface atoms and alter the binding energies of the electrons. This change in binding energy can be detected in the XPS spectrum and may provide information about the chemical interaction between Cr(VI) and the magnetite surface.
