Efficient removal of endosulfan from aqueous solution by UV-C/peroxides: A comparative study

Degradation kinetics and mechanism of oxytetracycline by hydroxyl radical-based advanced oxidation processes

“…Advanced oxidation processes (AOPs) via the generation of highly reactive free radicals, such as hydroxyl radical (HO • ) and sulfate radical (SO 4 •− ), have been considered as a promising alternative for the destruction of recalcitrant organic pollutants [16][17][18][19]. Hydroxyl radical-based AOPs (HR-AOPs) are a traditional and highly efficient process, because HO • is a non-selective oxidant ( V 2.72 E 0 = , depending on the experimental conditions [18]) having high second-order rate constants with organic compounds in the range of 10 8 -10 10 M −1 s −1 [20].…”

Prediction of key structural features responsible for aromaticity of single-benzene ring pollutants and their photooxidative intermediates

“…The effectiveness of UV-C/H 2 O 2 process, the most studied photochemical AOP, for the treatment of a vast array of organic pollutants, either simple-(e.g. single benzene ring) or complex-structured, is well documented [11][12][13][14][15][16][17], as well as its full-scale applications [18][19][20]. Since the complete mineralization of organic contaminants by AOPs might be costly, their application can be aimed at the elimination of targeted refractory organics (mainly of aromatic structures), thus increasing biodegradability and lowering toxicity and aromaticity of the treated water, which are often cross-correlated [21].…”

An overview on the advanced oxidation processes applied for the treatment of water pollutants defined in the recently launched Directive 2013/39/EU

“…For instance, atrazine (Khan et al, 2014) and endosulfan (Shah et al, 2013) at initial concentrations of 1 mg L − 1 and 350-1500 mg L − 1 , respectively, were degraded by direct photolysis at 254 nm and the removal efficiency was enhanced using different peroxides, being persulfate the most efficient peroxide in both cases.…”
