Oxytetracycline Water Contamination Treated with Biocarbon TiO2 and Solar Photodecomposition

Abstract

Reliable data of antibiotic use and environmental discharge as veterinary medicine are essential to help countries raise awareness of the appropriate use, control, and correct water release. The first approach is to change the regulatory framework based on consuming information, use policy, and discharge laws. The important research contribution is a novel water treatment process to treat, remove, and reduce antibiotic concentration in discharged water, mainly those used in the animal protein industry. The low particle biochar added during the titanium isopropoxide hydrolysis reduces the titanium dioxide (TiO 2) agglomerates and promotes the adsorption surface process. Such improved catalyst material enhances the solar decomposition efficiency to 93% from original oxytetracycline with better correspondence with the Elovich kinetics, intraparticle diffusion, R-P isotherm, and Langmuir-Hinshelwood model.

TiO<sub>2</sub>-PES Fibrous Composite Material for Ammonia Removal Using UV-A Photocatalyst

“…Furthermore, TiO 2 has consistently been employed as a photocatalyst for redox reactions and has been extensively documented in scientific literature [23] [24] [25] [26]. However, it is imperative to acknowledge that the use of TiO 2 particles as photocatalysts, particularly in slurry systems, poses challenges concerning the recovery of TiO 2 particles from the treated water medium [27]. The uncollected slurry can introduce environmental contamination concerns, which necessitate resolution.…”
