Modeling the reaction kinetics of Fenton’s process on the removal of atrazine

Removal of ten pesticides from leaching water at pilot plant scale by photo-Fenton treatment

“…For this, the ratio of FR at 0.5 was selected in this study. Similar findings were found by Chan and Chu [27] working with atrazine in a batch reactor. Likewise, they point out that at a fixed FR ratio, the higher the [Fe 2+ ], the faster and higher the fraction of atrazine degradation that is observed.…”

Acid dyebath effluent pretreatment using Fenton's reagent: Process optimization, reaction kinetics and effects on acute toxicity

“…Referring to the Fenton process, it is well known that a higher hydrogen peroxide (oxidant) to pollutant molar ratio results in more thorough substrate degradation; while higher concentrations of ferrous iron (catalyst) yield kinetically faster oxidation rates [32]. As previously mentioned, Fenton's reagent is employed to produce sufficient quantities of OH to degrade organic substances (R) at diffusion limited rates (k R,OH ¼ 10 7 e10 10 M ÿ1 s ÿ1 ).…”

On the Low‐Lying Excited States of sym‐Triazine‐Based Herbicides

“…[9][10][11] As a consequence, public concern has grown about the long-term environmental and health effects of such pollutants. [12,13] Many different techniques, including chlorination, [14] ozonation, [15] H 2 O 2 -promoted oxidation, [16] biological degradation, [17] Fenton oxidation, [18] radiolysis, [19] photocatalysis, [20] photosensitization, [21] and reduction, [22] have been attempted with questionable success to promote the degradation or elimination of these pollutants. A possible alternative is direct photodegradation, for which a number of studies on photoproducts have been performed, but little mechanistic information is available.…”
