Recent Advances in Advanced Oxidation Processes for Degrading Pharmaceuticals in Wastewater—A Review

Catalysts, Journal Year: 2024, Volume and Issue: 14(3), P. 189 - 189

Published: March 10, 2024

A large variety of pharmaceutical compounds have recently been detected in wastewater and natural water systems. This review highlighted the significance removing compounds, which are considered indispensable emerging contaminants, from Various advanced oxidation processes (AOPs), including UV-H2O2, Fenton photo-Fenton, ozone-based processes, photocatalysis, physical such as sonolysis, microwave, electron beam irradiation, regarded most viable methods to eliminate different categories discussed. All these AOPs exhibit great promising techniques, catalytic degradation process advantages, disadvantages each technique were deliberated. Heterogeneous photocatalysis employing metal oxides, particularly anatase TiO2 nanoparticles catalysts activated by UV light was reviewed terms electron–hole separation, migration charge carriers catalyst surfaces, redox potential carriers. brief overview also emphasized that TiO2-based nanomaterials photocatalysts, a combination other enhanced photocatalytic efficiency. Finally, challenges applying environmental remediation treatments degrade mass spectroscopic analysis biological activity test by-products contaminants resulting summarized.

Treatment of hospital wastewater by anodic oxidation using a new approach made by combining rotation with pulsed electric current on Cu-SnO2–Sb2O5 rotating cylinder anode

Heliyon, Journal Year: 2025, Volume and Issue: 11(2), P. e42069 - e42069

Published: Jan. 1, 2025

A high-efficiency, low-cost Cu-SnO2-Sb2O5 anode was prepared using a novel approach that combines the effects of rotation with pulsed current. The operating variables such as speed (50-250 rpm), current density (5-20 mA/cm2), and electrodepostion time (30-60 min) on morphology activity were investigated. structure examined by SEM, EDS, XRD techniques. results showed higher combined gave better properties in terms oxidation longer service life time. optimum conditions for preparing 10 mA/cm2, 250 rpm, deposition 60 min. has ability to remove methylene blue (MB) an efficiency 99.7 %. It excellent 30 h. Additionally, potential COD from hospital wastewater 85 % applying mA/cm2 120 min at initial pH 3 where energy consumption 2.85 kWh/kg claimed. combining electric offers enhanced degradation extended life, demonstrating industrial-scale treatment.
