This study investigated the elimination of Cr(VI) from aqueous solution utilizing a composite from magnetic nanoparticles (Fe3O4) capped with cetyltrimethylammonium bromide (CTAB). The structure of the prepared composite system was examined by Fourier Transform Infra Red Spectroscopy (FTIR). X-ray Diffractometry (XRD). and Transmission Electron Microscopy (TEM). https://goodvibesbadhabiters.shop/product-category/silicone-vibrators/
