This study proposed a sequential redox process to partially degrade tetrabromobisphenol A (TBBPA) within reactor great extent. After 72 hours in an anoxic environment, 20 ppm of TBBPA could be effectively degraded by sulfurized zerovalent iron nanoparticles (S-nZVI) at concentrations 2 g L-1 and 4 L-1. Biphenol (BPA) together with tri-, di-, monobromobisphenol was detected high-performance liqu...

Abstract Passivation of nanoscale zerovalent iron hinders its efficiency in water treatment, and loading another catalytic metal has been found to improve the significantly. In this study, Cu/Fe bimetallic nanoparticles were prepared by liquid-phase chemical reduction for removal hexavalent chromium (Cr(VI)) from wastewater. Synthesized characterized transmission electron microscopy, Brunauer–E...

Background and purpose: In recent years, the presence of antibiotics in aquatic environment has received increasing attention. These compounds remain in the environment, because of incomplete elimination in conventional wastewater treatment processes. Advanced oxidation processes are used to remove many pollutants. The aim of this study was to evaluate the efficiency of sono-fenton degradation ...
