Heterogeneous Fenton oxidation of paracetamol in aqueous solution using iron slag as a catalyst: Degradation mechanisms and kinetics

Kinetic insights on wet peroxide oxidation of caffeine using EDTA-functionalized low-cost catalysts prepared from compost generated in municipal solid waste treatment facilities

“…The technology shows a great potential for the degradation of many micro-pollutants (e.g. pharmaceuticals, personal care products, steroid hormones, among other emerging compounds) (Van et al, 2020), as previously demonstrated (Huaccallo-Aguilar et al, 2021;Santos Silva et al, 2019). Among those compounds, caffeine has gained increased attention, due to its consumption in beverages, dietary supplements and medications, and to its persistence in aquatic environment, since caffeine degradation through biodegradation and/or photolysis is poor (Keerthanan et al, 2020;Paiga et al, 2019;Richardson and Kimura, 2017;Korekar et al, 2020).…”

Reutilization of Fe-containing tailings ore enriched by iron(iii) chloride as a heterogeneous Fenton catalyst for decolorization of organic dyes

“…The mineralization of paracetamol also decreased at the H 2 O 2 /Fe 2+ of 1 : 3. 44 From these results, the catalyst dosage of 0.5 g L −1 was chosen for conducting further degradation experiments in this work.…”

Synthesis, characterization, and application of α‐Fe2O3@TiO2@SO3H photo‐Fenton catalyst for photocatalytic degradation of biologically pre‐treated wood industry wastewater

“…However, there are some limitations for this process such as sludge production, limited range of pH (2.5–3.5), H 2 O 2 scavenger, great iron release to the environment, and difficulty of the recovery of iron ions (Akhavan & Azimirad, 2009; Peng et al, 2010). Heterogeneous Fenton catalysts such as iron oxides (Hua et al, 2014; Lee et al, 2012; Thabet et al, 2021; Tony & Lin, 2020, 2021; Van et al, 2020; Yoo et al, 2017; H. Zhang et al, 2017) and iron‐immobilized substances (Lee et al, 2012; Yang et al, 2015) can be alternative methods for the treatment of organic pollutants. The heterogeneous Fenton catalysts can oxidize aqueous pollutants at a wider range of pH (Lee et al, 2012).…”
