Enhanced activation of PMS by a novel Fenton-like composite Fe₃O₄/S-WO₃ for rapid chloroxylenol degradation.

ABSTRACT: Chloroxylenol (PCMX) is widely used as disinfectant since the epidemic outbreak due to its effective killing of Covid-19 virus. Its stable chemical properties make it frequently detected in surface water. Herein, we successfully modified Fe₃O₄ nanoparticles with S-WO₃ (X-Fe₃O₄/S-WO₃) to accelerate the Fe²⁺/Fe³⁺ cycle. The composite has outstanding PCMX degradation and peroxymonosulfate (PMS) decomposition efficiency over a wide pH range (3.0 ∼ 9.0). 80-Fe₃O₄/S-WO₃/PMS system not only increased PMS decomposition efficiency from 27.7% to 100.0%, but also realized an enhancement of PCMX degradation efficiency by 16 times in comparison with that of Fe₃O₄
