Persulfate and Hydrogen Peroxide-Activated Degradation of Bisphenol A with Nano-scale Zero-valent Iron and Aluminum

Abstract In the present study, hydrogen peroxide (HP) and persulfate (PS)-activated nanoscale zero-valent iron (nZVI) and zero-valent aluminum (nZVAl) heterogeneous treatment systems (nZVI/HP-PS and nZVAl/HP-PS) were investigated for the removal of 20 mg/L (88 μM) aqueous Bisphenol A (BPA). Oxidation with HP and PS in the absence of nanoparticles did not cause BPA degradation, whereas the nZVI/O
