“…EE/O= (kWh m -3 /order ) (7) where: P is the electrical power input (kW), V is the volume of effluent used (L), k -rate constant of first-order kinetics (min -1 ). (8). Moreover, apart from the main effect of HO * , it is necessary to take into account the simultaneous effects of UV radiation even though direct quantum photonic activity is not high.…”

Nitramine compounds (NAs), such as hexogen (cyclotrimethylene trinitramine, RDX), octogen (cyclotrimethylene trinitramine, HMX), tetryl (2,4,6-trinitrophenyl-N-methylnitramine, TET) are commonly used as explosives. Their molecular structures are described in Table 1. These nitramine compounds contaminate wastewater from some industrial explosive production lines that make ammunition for military use. TET is mainly employed as a booster charge to propagate detonation in the main charge, while RDX and HMX are used in bombs, torpedoes, and armour-piercing shells. NAs cause harm to human health, animals, and ecosystems. Lewis-Younger et al. (2000) investigated the toxic effect of nitramine explosives on workers in explosives plant; their results showed that TET caused dermatitis in 61 of the employees. At the same time, RDX was identified as the cause of nausea, dizziness, convulsions, vomiting, and headaches. Some by-products of RDX and HMX degradation are carcinogens or mutagens; for example,

“…Thus, the reported effect of solar UV can be higher on a tilted surface and solar collectors. Also, Additives (Casado et al 2021) and photocatalysts (Roshith et al 2021) are other methods to enhance disinfection power and decrease disinfection time and solar UV dose.…”

“…As a result, there is no restriction on mass transfer (Lai et al 2021;Li and Cheng 2021). In numerous investigations, iron salts have been used successfully in the photo-Fenton method to treat a variety of resistant wastewaters (Casado et al 2021;Yang et al 2021a). Although homogeneous photo-Fenton has a high mineralization efficiency under ideal conditions, it has some drawbacks.…”

“…The most critical parameters that impact the efficacy of pollutant removal in the photo-Fenton oxidation process are the initial concentrations of the pollutant and Fenton reagents, acidity, and temperature of the mixture solution (Casado et al 2021;Li and Cheng 2021;Nippes et al 2021). In this case, optimizing the reaction is critical to achieving improved treatment outcomes.…”

Solar photo-oxidation of recalcitrant industrial wastewater: a review

et al. 2022

View full text Add to dashboard Cite

Conventional methods to clean wastewater actually lead to incomplete treatments, calling for advanced technologies to degrade recalcitrant pollutants. Herein we review solar photo-oxidation to degrade the recalcitrant contaminants in industrial wastewater, with focus on photocatalysts, reactor design and the photo-Fenton process. We discuss limitations due to low visible-light absorption, catalyst collection and reusability, and production of toxic by-products. Photodegradation of refractory organics by solar light is controlled by pH, photocatalyst composition and bandgap, pollutant properties and concentration, irradiation type and intensity, catalyst loading, and the water matrix.
