Due to its deleterious effects on health, development of new methods for detection and removal of pesticide residues in primary and derived agricultural products is a research topic of great importance. Among them, imazalil (IMZ) is a widely used post‐harvest fungicide with good performances in general, and is particularly applied to prevent green mold in citrus fruits. In this work, a composite film for the impedimetric sensing of IMZ built from metal‐organic framework nanocrystallites homogeneously distributed on a conductive poly(3,4‐ethylene dioxythiophene) (PEDOT) layer is presented. The as‐synthetized thin films are produced via spin‐coating over poly(ethylene terephtalate (PET) substrate following a straightforward, cost‐effective, single‐step procedure. By means of impedance spectroscopy, electric transport properties of the films are studied, and high sensitivity towards IMZ concentration in the range of 15 ppb to 1 ppm is demonstrated (featuring 1.6 and 4.2 ppb limit of detection, when using signal modulus and phase, respectively). The sensing platform hereby presented could be used for the construction of portable, miniaturized, and ultrasensitive devices, suitable for pesticide detection in food, wastewater effluents, or the assessment of drinking‐water quality.

“…Recently, the use of ferrates VI as a water treatment to oxidize organic pollutants (laboratory experiments) has been well documented. This strong oxidant reacts on a wide range of agents as pharmaceuticals, pesticides, phenols, cyanide, heavy metals, microorganisms, natural organic matter (Bielski et al, 1994;Filip et al, 2011;Gan et al, 2015;Hrabak et al, 2016;Jiang et al, 2006;Johnson and Sharma, 1999;Liu et al, 2019;Manoli et al, 2019;Peings et al, 2017Peings et al, , 2015Rai et al, 2018;Sharma, 2013Sharma, , 2008Yngard et al, 2008), and aromatic structures like BTEX (Lacina and Goold 2015;Minetti et al 2017), water lixiviates from bitumen (Wang et al, 2016) and PAHs (Guan et al, 2014). It releases O2, HOand ends as Fe(OH)3, which has flocculent properties and is nontoxic towards the environment.…”

“…Ferrate(VI) is a highly-efficient wastewater treatment reagent that can be used as an effective oxidant, coagulant, demulsifier, disinfectant, and cathode material [25]. There has been an increasing amount of interest to activate Fe(VI) to enhance the oxidation of pharmaceuticals and pesticides [26]. In addition, ferrate(VI) can also rapidly oxidize inorganic and organic contaminants with the addition of one-electron and two-electron transfer reductants [27,28,29].…”

Fracturing wastewater is often highly emulsified, viscous, and has a high chemical oxygen demand (COD), which makes it difficult to treat and recycle. Ferrate(VI) is a green oxidant that has a high redox potential and has been adopted for the efficient oxidation of fracturing wastewater to achieve triple effects: demulsification, visbreaking, and COD removal. Firstly, optimal conditions were identified to build a model for fast and efficient treatment. Secondly, wastewater treatment using ferrate oxidation was investigated via demulsification, visbreaking, and COD removal. Finally, a mechanism for ferrate oxidation was proposed for the three effects using Fourier-transform infrared (FT-IR) spectroscopy and scanning electron microscopy (SEM). The theoretical and experimental data demonstrated that the ferrate oxidation achieved the three desired effects. When ferrate was added, the demulsification efficiency increased from 56.2% to 91.8%, the total viscosity dropped from 1.45 cp to 1.10 cp, and the total removal rate of COD significantly increased to 74.2%. A mechanistic analysis showed that the strongly-oxidizing ferrate easily and efficiently oxidized the O/W interfacial film materials, viscous polymers, and compounds responsible for the COD, which was a promising result for the triple effects.
