“…These chemical compounds are used in numerous industrial processes, and they are considered as extremely toxic and carcinogenic (Chaturvedi and Katoch 2020b). Chaturvedi and Katoch (2020a) used Fenton oxidation for removing methoxyanilines with a concentration of 0.5 mM. The results showed removal efficiencies of 83 %.…”

The reuse of treated wastewater (TWW) has been considered a suitable alternative for agriculture and for achieving water security and management. However, this practice may contribute to the dissemination of antibiotic resistance genes (ARGs) into the environment, a matter of global concern. The aim of this study is to discuss the reuse of TWW in agriculture under the perspective of the risks associated to ARGs dissemination. An exhaustive bibliographic research was conducted for determining the capacity of reducing ARG loads for different wastewater treatment technologies (conventional, non-conventional and advanced technologies). Moreover, the distribution of ARG elements in crops irrigated with TWW was also reviewed for discussing the potential health risks associated to the TWW reuse. Reduction of ARG loads in conventional, non-conventional and advanced treatments fluctuated between 1.1 and 4.1, 0.1-2.1 and 0.1-9.5 log units, respectively. These variable ranges indicate that operational parameters, plant design, and water quality are fundamental parameters determining their performance and their capacity to reduce ARG dissemination. In the case of ARG distribution in crops and soil irrigated by TWW, higher abundances were observed in soil than edible parts of crops with ranges between (-0.7)-6.0 log copies/g of soil and (-0.9)-5.6 log copies/g of soil, respectively. The occurrence of ARGs in crops may represent a relevant human exposure to ARG-harbouring bacteria and therefore, a potential human health risk that requires the establishment of safe procedures and legislation for assuring a safe reuse of TWW.

“…As the most promising methods, advanced oxidation processes, such as Fenton reactions, photocatalysis, electrocatalysis, ozone oxidation, etc., are often used to deal with refractory organic compounds in water which can produce a lot of hydroxyl radicals with strong oxidizing activity [13][14][15][16][17][18]. Fenton reactions, including all kinds of Fenton-like reactions, have become a research hotspot in the field of water treatment due to its high degradation efficiency, mild reaction conditions, low energy consumption, and simple operation [19][20][21][22]. In particular, the heterogeneous Fenton method has the advantages of wide pH range, low H 2 O 2 and catalysts consumption, easy separation, and no secondary pollution with high removal ratios [23][24][25][26].…”

A heterogeneous particle catalyst (CuO-Fe2O3/CTS-ATP) was synthesized via injection molding and ultrasonic immersion method, which is fast and effective. The particle catalyst applied attapulgite (ATP) wrapped by chitosan (CTS) as support, which was loaded dual metal oxides CuO and Fe2O3 as active components. After a series of characterizations of catalysts, it was found that CuO and Fe2O3 were successfully and evenly loaded on the surface of the CTS-ATP support. The catalyst was used to degrade methylene blue (MB) and ciprofloxacin (CIP), and the experimental results showed that the degradation ratios of MB and CIP can reach 99.29% and 86.2%, respectively, in the optimal conditions. The degradation mechanism of as-prepared catalyst was analyzed according to its synthesis process and ∙OH production, and the double-cycle catalytic mechanism was proposed. The intermediate products of MB and CIP degradation were also identified by HPLC-MS, and the possible degradation pathways were put forward.

“…At present, many technologies have been employed to the treatment of OBDC, including continuous supercritical water oxidation, solvent washing, surfactant-based washing, demulsification, pyrolysis, biotreatment, and Fenton oxidation (Adhami et al 2021;Chen et al 2020;Cheng et al 2020;Hu et al 2021;Poyai et al 2020;Yan et al 2011;Ye et al 2017). Among these methods, Fenton oxidation has been widely employed for treatment of oil-contaminated soil and water (Akpoveta et al 2018;Chaturvedi and Katoch 2020a;Chaturvedi and Katoch 2020b;Vilar et al 2020;Xu et al 2020;Xu et al 2017). However, the efficiency of direct Fenton oxidation for OBDC treatment is limited due to the complex emulsification oil-water interface during the reaction process (Wang et al 2017).…”

In this study, demulsification separation-Fenton oxidation technology was employed as a combined technology to treat total petroleum hydrocarbons (TPH) in oil-based drill cuttings (OBDC). Batch experiments were carried out to optimize the technology parameter. Under the optimal condition, 70% and 51% TPH removal rate was obtained for demulsification technology and Fenton oxidation technology, respectively. Eighty-five percent of TPH removal rate was obtained using combination technology of demulsification separation and Fenton oxidation. Multiple characterizations were used to analyze the physical and chemical properties of treated OBDC. The result of XRD pattern indicated the combination technology had no obvious effect for structure phase of OBDC. The results of FTIR, GC-MS, TG-DTG and SEM were used to characterize the treated OBDC. This paper provides an efficient and feasible combined technology for OBDC treatment, which expands a new strategy for the removal of TPH from solid waste
