“…This result was obtained previously by Schaller et al [70], who found that Si improved nutrient uptake capability, thereby improving soil fertility. In addition, Romeh and Hendawi [37] reported that the combination of Glycine max plus SiO 2 was better than other solubility-enhancing surfactants (Argal) for reducing the level of fenamiphos in soil. However, the function of SiO 2 in terms of enhancing the phytoremediation of soil polluted with pesticides is still required.…”

“…One gram of soil was added to all of these solutions and incubated with shaking for 3 h; then, the resulting suspensions were kept at 27 °C for 24 h. The suspensions were centrifuged at 15,000 rpm for 10 min, and the amount of CYP in supernatants were analysed by gas chromatography with an electron capture detector (GC-ECD) to determine the amount of CYP in the supernatants. According to Romeh and Hendawi [37], the amount of adsorbed CYP was calculated as the difference between the initial concentration of CYP and the concentration at equilibrium: where x/m is the CYP concentration in the soil (µg g −1 ), C 0 is the initial concentration of CYP (µg mL −1 ), C e is the (1)…”

“…It also plays an essential role in improving plant resistance to stress, which can be achieved by accumulating silicon in plant parts, including hulls, leaves, stems, and roots [36]. Moreover, the phytoremediation efficiency of Glycine max amended with SiO 2 is better than that of Argal in the removal of fenamiphos residue from contaminated soil [37]. Few reports have focused on the role of SiO 2 in improving pesticides uptake and the availability in contaminated soil.…”

Background: Surfactant-enhanced phytoremediation is an eco-friendly treatment for reducing soil contamination. Cypermethrin (CYP) is one of the most widely used pyrethroid insecticides against different pests, and its use causes soil contamination. The aim of this study was to investigate the removal of CYP from contaminated soil by Plantago major (PM) and some surfactants. For the first time, we documented the uptake and translocation of CYP from the soil and used some strategies to improve the effectiveness of this technology, which involved the use of various surfactants to solubilize the contaminant. In a pot experiment, four surfactants [liquid silicon dioxide (SiO 2 , 750 mg L −1 ), 2-hydroxypropyl-beta-cyclodextrin (HPßCD, 1%), humic acid (HA, 10 mg L −1 ) and Tween 80 (Tw80, 9.2 mg L −1 )] were used to facilitate the phytoremediation of CYP (10 µg g −1 )-contaminated soil by PM.Results: Our data showed that amending the soil with PM plus SiO 2 significantly reduced the amount of CYP in the soil and highly increased the concentrations of CYP in the plant roots and leaves. The longest half-life value (t 1/2 ) of CYP was in the sterilized soil treatment (24.8 days), and the shortest was in the soil with PM amended with SiO 2 (6.41 days). The half-life value (t 1/2 ) of CYP in soil with PM alone was 10.0 days. Through in vitro experiments, a batch equilibrium technique showed that hydroxypropyl-ß-cyclodextrin (HPßCD) is the best surfactant to most efficiently eliminate CYP from the soil. However, in the greenhouse experiment, the addition of SiO 2 to soil cultivated with PM was more effective than the use of other solubility-enhancing surfactants in the removal of significant amounts of CYP (p > 0.05) from the contaminated soil. Conclusions:The integration of SiO 2 + PM is the best treatment and is recommended for minimizing plant contaminant contents in CYP-contaminated soil. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

Electrochemically Reduced Graphene Oxide as Screen‐printed Electrode Modifier for Fenamiphos Determination

In this study, electrochemically reduced graphene oxide (ERGO) was used for the preparation of a screen‐printed modified electrode and applied for the voltammetric determination of fenamiphos (FNP) in tomato samples. Graphene oxide (GO) used for sensor construction was prepared according to an improved Hummers method and characterized by XRD, TEM, and FTIR, which confirmed the nanomaterial obtention. The ERGO formation was carried out from the electrodeposition by cyclic voltammetry, at 50 mV s−1 in the potential range of 0.0 to −1.5 V, during 50 cycles. ERGO‐SPE was used in the evaluation of the voltammetric behavior of FNP. The ERGO‐SPE proposed presented excellent electrochemical performance towards FNP oxidation, promoting an enhance on the anodic peak current and a decrease of peak potential. Under optimized conditions, it was possible to construct an analytical curve, using square wave voltammetry, with a linear region of 0.25 to 25.0 μM, with calculated limits of detection and quantification of 0.067 and 0.22 μM. From this, it was possible to analyze FNP in fortified tomato samples at three concentration levels, which showed recoveries values varying between 82 and 102 %. The ERGO‐SPE device proved useful in determining FNP, where the effect of the electrodeposition of the GO promoted a significant increase in the employability of the printed electrode.
