Abstract

Hydrogen peroxide (H2O2) catalyzed by ultraviolet light (UV) radiation is an advanced oxidation process (AOPs) that degrades trace organic compounds present in wastewater. Treatments involved using different H2O2 concentrations in solar-simulated UV (lab scale) and solar-UV (outdoors) systems. Percent degradations of fluorescein and methylene blue were measured using absorbance of the samples to find compound concentration over time as the reaction progresses. The lab scale treatment involves a 120 watt solar-simulated UV lamp at 254 nm. In the solar UV treatment, solution mixtures were placed outdoors in sunlight during peak hours between 10am-2pm, around mid August. This study’s objective is to quantify the efficiency of H2O2/UV in degrading organic contaminants with fluorescein and methylene blue. In the lab scale treatments, concentration removal percentages for fluorescein was 45.1% and methylene blue was 44.2%. This AOP offers an eco-friendly and efficient alternative to degrading trace organic compounds in wastewater. Integrating AOPs in current wastewater methods may lead to more resource efficient treatments for higher water quality, subsequently improving ecosystem health.
