Optimization of p-Nitrophenol Degradation and Mineralization Using a Photochemical Reactor
Advanced oxidative processes are widely used in the degradation of organic compounds. The degradation and mineralization of the PNF was evaluated using an experimental factorial design, using photolysis (UV) and photo-peroxidation (UV/H 2 O 2 ). With the results optimized, degradation kinetics was p...
