The formation and influence of hydrogen peroxide during ozonation of para-chlorophenol

Catalytic ozonation for the removal of organic contaminants in water on alumina

“…VOCs are regulated pollutants that have been detected in drinking water [15]. Chlorinated aromatic compounds are highly toxic, widely used and are known to be highly resistant to ozonation [16]. Pharmaceuticals are emerging and still unregulated pollutants.…”

Sulphonated cobalt phthalocyanine–MCM-41: An active photocatalyst for degradation of 2,4-dichlorophenol

“…Contamination by chlorinated phenols is currently one of the most serious environmental problems and constitutes the most important family of toxic non-biodegradable compounds [1]. These contaminants are generated from a number of industrial manufacturing processes such as pesticide, paint, solvent, pharmaceutical, wood preserving chemicals and pulp industries [2]. Various treatment strategies are applied for the removal of toxic organic contaminants such as chlorophenols [3][4][5].…”

Sunlight mediated removal of chlorophenols over tungsten supported ZnO: Electrochemical and photocatalytic studies

“…Among the water contaminants, chlorophenols are the most 11 hazardous class of water pollutants [1][2][3][4][5][6]. For human consump- 12 tion, the recommended levels of various chlorophenols in water 13 are below 0.1 mg/l [1].…”
