Coffee husk

In this study, a composite material between MnFe2O4 and activated carbon from coffee husks (MFO/AC) was synthesized using co-precipitate and hydrothermal methods to remove ammonium from aqueous solutions. The characteristics of MFO/AC were characterized and evaluated by scanning electron microscopy (SEM) and Fourier transform infrared spectra (FTIR).
