Equilibrium, kinetic and thermodynamic studies of removal of phenol from aqueous solution using surface engineered chemistry
Iron impregnated activated carbon has been used as a new adsorbent for the adsorptive removal of phenol from waste water. Impregnation of iron was confirmed by Fourier transform infrared spectroscopy and scanning electron microscope and energy dispersive spectroscopy. Different parameters affecting...
