“…In the recent decade, other metals apart from iron have been used (Mahamallik & Pal 2016;, termed as Fenton-like processes. Apart from H 2 O 2 , other chemicals such as peroxymonosulfate have also been practised to generate powerful radicals for oxidation (Kakavandi et al 2022). The use of stable oxidants such as calcium peroxide has also been documented in some reports (Ali et al 2020a(Ali et al , 2020b(Ali et al , 2021.…”

Synthetic organic pollutants emanating continuously in the ecosystem have become a global concern because of their toxicity and persistent nature. Bisphenol A (BPA) is one such pollutant which threatens public health and safety. It is a monomer used in manufacturing plastics, polycarbonate resins, epoxy resins and is a well-recognised endocrine disruptor miming estrogen. BPA leaches into food and beverages stored in containers causing contamination issues. Its widespread exposure and potential toxicity is an environmental health concern. In this review, a systematic investigation has been carried out on the heterogeneous catalysts used for Fenton-like processes for BPA degradation. The Fenton-like reaction is one such reaction that is used for wastewater remediation purposes. The reaction advances through the generation of powerful oxidizing radicals like OH. and SO4•– in the presence of a suitable catalyst. The application of various Fenton catalysts, with their distinguished morphological characteristics, oxidizing properties, toxicity analysis, and the present state of the art of BPA degradation by these catalysts, have been documented in the current work. This review also highlights a few challenges and prospects for analysing degradation products of landfill leachate.

“…The plant molecules’ interaction over the cobalt and iron source materials constructed the electron mitigation in the UV region. The bandgap of CoFe 2 O 4 nanoparticles was calculated from the Kubelka–Munk relation [ 34 , 35 ], with the CoFe 2 O 4 nanoparticles having a bandgap value of 2 eV ( Figure 3 b). This narrow bandgap value presents the highest e–h pair recombination activity and enhanced degradation behaviour [ 36 ].…”

Biogenic CoFe2O4 nanoparticles were prepared by co-precipitation and Hibiscus rosa sinensis plant leaf was used as a bio-reductant of the nanoparticle productions. The biosynthesized CoFe2O4 nanoparticles were characterized by XRD, FTIR, UV, VSM, and SEM via EDX analysis. The cubic phase of biosynthesized CoFe2O4 nanoparticles and their crystallite size was determined by XRD. The Co-Fe-O bonding and cation displacement was confirmed by FTIR spectroscopy. The presence of spherically-shaped biosynthesized CoFe2O4 nanoparticles and their material were confirmed by SEM and TEM via EDX. The super-paramagnetic behaviour of the biosynthesized CoFe2O4 nanoparticles and magnetic pulse was established by VSM analysis. Organic and bacterial pollutants were eradicated using the biosynthesized CoFe2O4 nanoparticles. The spinel ferrite biosynthesized CoFe2O4 nanoparticles generate radical and superoxide ions, which degrade toxic organic and bacterial pollutants in the environment.

“…[18][19][20] However, very few researches focus on the decomposition of these compounds in aqueous solutions. In this study, to understand the formation and stability of peroxymonocarbonate HCO4in the H2O2 + HCO3 -+ Co(II) system (with the presence of Co(II) ion), permanganate titrations were utilized to monitor the variation of HCO4 -+ H2O2 concentration over time, via the titration reaction: 5H2O2 + 2MnO4 -+ 6H + → 2Mn 2+ + 5O2 + 8H2O (5).…”

Decolorization of Rhodamine B (RhB) by peroxymonocarbonate (HCO4–) in aqueous solution was investigated in this study. All experiments were conducted in a 50 mL batch reactor at room temperature (26 ± 1°C) and pH of 9.0. The oxidizing agent (peroxymonocarbonate) was prepared in‐situ by the reaction between hydrogen peroxide and bicarbonate (molar ratio of H2O2:HCO3– is 2:1). The catalytic effect of four metal ions including Co(II), Cu(II), Fe(II), Mn(II) on the decolorization by HCO4– was evaluated. Co(II), the metal ion giving the best catalytic effect, has been selected to study the stability of peroxymonocarbonate agent. To clarify the role of H2O2 and HCO4– in oxidizing RhB dye, a series of experiments were conducted at different concentrations of HCO3‐ and Co(II) catalyst. UV and ultrasound irradiations were also tested for enhancing the decolorization rate. The results revealed that in the presence of Co(II) ion, HCO4– becomes more reactive and a synergic effect on the RhB degradation has been observed when both Co(II) and HCO4– are present in the oxidation system. And under UV light, complete decolorization of RhB by peroxymonocarbonate agent could be obtained after only 20 minutes of irradiation.
