USE OF SOME METAL FERRITES IN THE REDUCTION OF 2,4,6-TRINITROPHENOLSHUBANG VYAS, NEHA GODHA, RAKSHIT AMETA1 AND SURESH C. AMETAAbstract The noble-metal Nanocatalyst are widely used, but ferrite-based magnetic catalyst are rarely used.The magnetic copper ferrite, CuFe2O4 catalyst was synthesized by hydrothermal method and usedto reduce 2,4,6-trinitrophenol in presence of sodium borohydride. The copper ferrite was analysedby X-ray diffraction spectroscopy (XRD), Energy-dispersive X-ray spectroscopy (EDX), ScanningElectron Microscopy (SEM) and Fourier transform infrared (FTIR). The reduction of 2,4,6-trinitrophenol was observed in presence of copper ferrite as catalyst and sodium borohydride asthe reductant. The conversion of 2, 4, 6-trinitrophenol to 2, 4, 6-trimenophenol was monitored byUV-Visible spectrophotometer. The effect of various parameters such as pH, concentration of nitrocompound, and amount of catalyst were studied. The reaction was completed in 8 min in thepresence of copper ferrite. It was interesting to note that copper ferrite exhibited higher rate ofreduction in present of zinc and nickel ferrites, may due to synergetic effect otherwise they showvery slow reduction. |
