The performance of the persulphate/Mn 3 O 4 nanoparticles (PS/Mn 3 O 4 ) oxidation process was investigated for the degradation of acid blue 113 (AB113) azo dye. XRD, N 2 adsorption-desorption analysis, FE-SEM and EDX confirmed the successful synthesis of Mn 3 O 4 nanoparticles. The effect of three...
