New method removes phenol from wastewater with 99% efficiency in 30 minutes.
The study tested a method to clean water contaminated with phenol using UV/Fenton oxidation. By adjusting factors like H2O2 amount, Fe2+ concentration, and pH level, they found that a pH of 3.0 led to 99% phenol removal and 86% COD removal in just 30 minutes. The method is effective at quickly cleaning phenol and COD from water, with H2O2 and Fe2+ levels playing a big role in its success.
