摘要：

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). Separation of the Fe3O4/CTAB composite from the wastewater can be achieved by application of an external magnetic field. Factors affecting the Cr(VI) expulsion from wastewater such as pH, competing ions, the dosage level of the nanoparticles, and contact time were studied. The results indicated that the maximum efficiency of the present system for removal of Cr(VI) (95.77%) was in acidic conditions (pH 4), contact time 12 h, and composite dosage of 12 mg/mL. The used Cr(VI) concentration was 100 mg/L. Considering results, the Fe3O4/CTAB system showed a high capability and selectivity for the treatment of water sullied with Cr(VI). This can recede the mutagenic and carcinogenic health risk caused by Cr(VI) water tainting. (C) 2017 Production and hosting by Elsevier B.V. on behalf of Cairo University.
