“…Because a homogeneous solution is utilized, the light penetration depth is great, and the interaction between the contaminant and oxidizing catalyst is effective. The low pH values required, which are often below pH = 4, and the requirement of iron removal after the reaction are disadvantages; however, both issues could be avoided using a post-treatment procedure (Della-Flora et al 2021;Wang et al 2021b).…”

Solar photo-oxidation of recalcitrant industrial wastewater: a review

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.
