Abstract The simultaneous use of persulfate (PS) and nano-Mn3O4 was investigated as an advanced oxidation process for furfural degradation and oil refinery wastewater treatment. The synthesized Mn3O4 nanoparticles were characterized by XRD, BET, BJH and FESEM-EDS and then successfully used as a heterogeneous catalyst for PS activation. The effects of five independent variables on the performance of nano-Mn3O4/PS system were investigated and optimized using a 5-level-5-factor full Central Composite Design (CCD). Accordingly, CCD developed a reduced quadratic polynomial model with P-value
