“…The above stability was not observed for Fe 3 O 4 /CNTs nanoparticles, checked by Eskandari Makvand et al [53] to remove 200 mL of 50 mg L −1 of malathion with 1.5 mM PS and 0.4 g L −1 of this photocatalyst in pure water at pH = 5.0 using a stirred tank photoreactor illuminated with a 24 W UV light. Although overall insecticide removal in 80 min with complete mineralization in 180 min was attained in this process (see Table 2), a low reusability was found after five consecutive mineralization cycles due to the poisoning of the photocatalyst surface.…”

“…As pointed out above, most works related to insecticides remediation from PS‐ and PMS‐based processes have been made with aqueous mixtures [31–58]. Thermal, catalytic, UV (without and with Fe), and photocatalytic activations, as well as other methods including electrochemical and microwave processes, have been majority developed at laboratory scale.…”

“…The photocatalytic activation of PS has been reported for the removal of methamidophos with TiO 2 [51], imidacloprid with TiO 2 /Fe 3 O 4 [52], malathion with Fe 3 O 4 /carbon nanotubes (CNTs) [53], and primicarb [54], and a mixture of insecticides [55] with ZnO. Photocatalysis (PC) involves the illumination of a semiconductor immersed into the polluted solution to promote the pass of an electron e CB − of its valence band (VB) to its conduction band (CB) giving a hole h VB + in the VB by reaction () [51, 56].…”

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.
