“…Water contaminated by pesticides has a challenge as it is not compatible with classical biological treatments, due to the high toxicity for the microorganisms involved in those processes, that is where AOPs can be used as a pre-treatment step, to convert inhibitory compounds into more easily biodegradable intermediates or to reduce their concentrations to the point where inhibition is not so significant (Liberatore et al 2012;Vela et al 2019) so current treatment techniques involve a combination of physical, chemical and biological methods for the removal of pesticides from water (Saleh et al 2020).…”

“…Photooxidation of ATZ allows the transformation of the pesticide into cyanuric acid establishing that this compound is not inhibitory to microorganisms, which proves the ability of AOPs to convert recalcitrant compounds into more biodegradable substances (Liberatore et al 2012;Vela et al 2019). However, (Benzaquén et al 2016) established that in the aerobic biological treatment the microbial population could not incorporate significant amounts of C or N from cyanuric acid, so the anaerobic process was where the removal of this by-product was achieved in 7 days.…”

“…Advanced oxidation processes (AOPs) have recently gained momentum, improving the prospects for treating wastewater with high pollutant loads (Delgado Nina & Santander Pacoricona 2017;Li et al 2021). They have been recognized as efficient alternatives for the removal of pesticides to acceptable levels (Affam & Chaudhuri 2019;Vagi & Petsas 2019;Vela et al 2018), decreased toxicity levels (Vela et al 2019), and improvements in effluent biodegradability (Ballesteros Martín et al 2010). However, AOPs as the sole treatment process requires considerable energy and chemical reagent costs (Oller et al 2011;Pazdzior et al 2019).…”

“…AOP-Biological couplings emerge as an alternative to reduce the limitations in advanced oxidation and enhance the results (Gernjak et al 2006). The configuration consists of converting the toxic waste liquid in the POA into another with more biodegradable and suitable characteristics for its subsequent degradation in biological reactors (Vela et al 2019), as validated by several studies (Lafi & Al-Qodah 2006;Berberidou et al 2017).…”

This article had the one and only objective of consolidating the couplings of advanced oxidation processes and biological in the decontamination of wastewater with pesticide content reported in the Scopus and Web of Science databases, through a critical analysis of which have been the most used, what methodologies have been implemented to develop them, identify the objectives of each work, determine the success of the research and where the main niches of knowledge are, which can lead to the generation of new scientific knowledge as well as future trends. A co-occurrence analysis was carried out through the VOSViewer software, to determine the most associated key words with the treatment configurations described above. Fenton and Photo-Fenton processes, heterogeneous photocatalysis TiO2/UV, electrocatalysis, ozonization and a particular case of hydrodynamic-ozone cavitation as main advanced oxidation processes, together with advanced biological processes such as SBR, MBR, MBBR; biodegradability and toxicity tests with bacterial strains and surface wetlands, whose treatment philosophy is activated sludge. The main future trends are the reuse of treated wastewater, the analysis and control of costs towards the efficient use of resources and the primary study of the byproducts generated in advanced oxidation to improve the efficiencies in the coupling.

“…Among the various semiconductors used for the photocatalytic applications, recently, cerium oxide (CeO 2 , commonly called ceria), a largely used catalyst in many thermo-catalytic reactions [17,18], was examined as an alternative to the most used metal oxide photocatalysts (such as TiO 2 and ZnO [19][20][21][22]). The most attractive properties of CeO 2 are: the lower band-gap (around 2.7-2.8 eV) compared to TiO 2 and ZnO, making the material sensitive to visible light; the presence of empty 4f energy levels that facilitate the electron transfers; the high stability in the reaction medium; the high oxygen mobility related to the reversible Ce 4+ /Ce 3+ transformation, and the ability to form nonstoichiometric oxygen-deficient CeO 2-x oxide [23].…”

CeO2 for Water Remediation: Comparison of Various Advanced Oxidation Processes

Three different Advanced Oxidation Processes (AOPs) have been investigated for the degradation of the imidacloprid pesticide in water: photocatalysis, Fenton and photo-Fenton reactions. For these tests, we have compared the performance of two types of CeO2, employed as a non-conventional photocatalyst/Fenton-like material. The first one has been prepared by chemical precipitation with KOH, while the second one has been obtained by exposing the as-synthetized CeO2 to solar irradiation in H2 stream. This latter treatment led to obtain a more defective CeO2 (coded as “grey CeO2”) with the formation of Ce3+ sites on the surface of CeO2, as determined by Raman and X-ray Photoelectron Spectroscopy (XPS) characterizations. This peculiar feature has been demonstrated as beneficial for the solar photo–Fenton reaction, with the best performance exhibited by the grey CeO2. On the contrary, the bare CeO2 showed a photocatalytic activity higher with respect to the grey CeO2, due to the higher exposed surface area and the lower band-gap. The easy synthetic procedures of CeO2 reported here, allows to tune and modify the physico-chemical properties of CeO2, allowing a choice of different CeO2 samples on the basis of the specific AOPs for water remediation. Furthermore, neither of the samples have shown any critical toxicity.

Removal of insecticides from waters and soils by sulfate radical‐based advanced oxidation processes

Insecticides are toxic compounds widely used to prevent, destroy, and control any insect pests. A larger food production with increasing agricultural activity has been ensured from their application to farmlands. Insecticides have been detected in waters and soils being dangerous for living beings. Due to their high biorecalcitrance and stability at ambient conditions, they cannot be destroyed in conventional wastewater treatment plants (WWTPs) and powerful advanced oxidation processes (AOPs) are being developed for their removal. This review presents a detailed and critical analysis over the application of sulfate radical‐based AOPs to the remediation of waters and soils polluted with insecticides. Persulfate (PS) and peroxymonosulfate (PMS) are used as parent oxidants but they need to be activated to produce strong effective oxidizing radicals such as sulfate radical (SO4●−) and hydroxyl radical (●OH). Alkaline, thermal, catalytic, UV, UV with Fe, photocatalytic, and other methods applied as activators of PS and/or PMS are separately analyzed in waters and soils. For each hybrid procedure, the fundamentals are briefly detailed and the best results reported in the literature are summarized and discussed. The effect of operating parameters on the oxidation power of treatments in pure water, real waters, WWTPs effluents, and contaminated soils are remarked to show the viability of sulfate radical‐based AOPs for insecticides removal from waters and soils. The effect of added common anions and natural organic matter, the detection of oxidizing radicals by selective scavengers and electron paramagnetic resonance, and the identification of the generated by‐products in waters are described. Comparisons with analogous treatments with H2O2 and Fenton are discussed as well. Further research efforts should consider a deeper study of PS‐ and/or PMS‐based processes of insecticides not only in actual agricultural and real wastewaters, but also in many soils to confirm their possible suitability at the industrial level.
