Abstract

Degradation of natural organic matter especially Humic acid is a big challenge, while its byproducts are carcinogenic, which is a threat to life. Here, Fe3+:ZnO has been deployed on ceramic plats (CP) using SILAR method for solar photocatalytic mineralization of HA in municipal wastewater. Structural results show that ZnO and Fe3+:ZnO deployed over CP have an average crystallite size of 47.43 nm and 29.54 nm, respectively. Further, Fe3+ doping increased the conductivity of ZnO due to enhanced photon capturing ability and effective surface area. Almost 90% HA photodegradation was achieved at the reaction parameters optimized by response surface methodology. Owing to the strong interaction bet..
