Chemical Wet Oxidation for the Abatement of Refractory Non-Biodegradable Organic Wastewater Pollutants

Degradation of acid red 97 dye in aqueous medium using wet oxidation and electro-Fenton techniques

“…Hydrogen peroxide (H 2 O 2 ) is a strong oxidant, and its application in the treatment of various inorganic and organic pollutants is well established. Numerous applications of H 2 O 2 are known in the removal of pollutants, such as sulfites, hypochlorites, nitrites, organic compounds and chlorine, from wastewater [42,43]. Hence, experiments were also realized with hydrogen peroxide to examine the effect of H 2 O 2 (116 mM) on the degradation of AR97 in wet peroxide oxidation system.…”

Perovskite-like catalysts LaBO3 (B = Cu, Fe, Mn, Co, Ni) for wet peroxide oxidation of phenol

“…In the recent years, a number of technologies (biological, thermal, chemical) have been developed for removal of toxic organic compounds from industrial wastewater [1,[3][4][5]. The process of catalytic wet peroxide oxidation (CWPO) is considered an alternative for the treatment of wastewater with moderate and relatively low concentrations of high-toxic organic compounds.…”

Enhanced adsorption of phenol from water by a novel polar post-crosslinked polymeric adsorbent

“…As per the World Health Organization regulation, 0.002 mg/L is the permissible limit for phenol concentration in potable water [3]. Many methods and technical processes including catalytic oxidation, biodegradation, solvent extraction and adsorption have been developed to treat the phenol-containing effluent [4][5][6][7][8][9]. On account of the high concentrating ability of typical adsorbents, adsorption is proved to be one of the most attractive and effective techniques for purification and separation in wastewater treatment [10,11].…”
