“…On the contrary, for DC current treatments, the electrical intensity increased a lot from the beginning of the application of the current until the first 4 hours, and then, after 8 h of current application, it decreased to slightly lower values than the initial ones (t = 0 h); it is the same trend previously described for the EC of the water sampled in electrode wells (Figure 3b). The electric current measured in electrokinetic remediation experiments has previously been shown to be related to ions flowing through the soil, moisture, porosity and electrochemical reactions occurring on the electrode surfaces [30]. Considering a similar magnitude for the electrochemical reactions in both electrodes, the variation of the ionic concentration of water in the electrode wells would cause the electric current changes observed in the treatments using DC current.…”

“…Many techniques have been developed to treat atrazine-contaminated water, including microbiological processes [6,7], electrochemical methods [8,9], photocatalysis [11,12], etc. Among them, photocatalysis has been given much attention because of its facility, efficiency, costeffectiveness, and utilization of solar energy.…”

Tungsten (W) and Cerium (Ce) doped nanoTitanium oxide (TiO2) nanophotocatalyst were prepared by the sol-gel method and their photodegradation effect against atrazine herbicide were investigated. The doping of the nanocatalyst took place at 50 °C within a time interval of 120 minutes. The prepared gel was dried and calcined in the oven at 350 °C for 75 minutes. The XRD result revealed that the synthesized nanocatalyst was 16.7 nm in size with a mostly monoclinic structure. With FTIR spectra, characteristic peaks of TiO2 were found at 516 cm-1, Ti-O-Ce at 1104 cm-1, and W-O with a single bond at 1609 cm-1. Scanning electron microscope analysis revealed the surface morphology of synthesized nanophotocatalyst. The photocatalytic activity of synthesized nanocatalyst was tested on the degradation of atrazine herbicide (ATZ) under visible and UV light in a batch reactor. The efficiency of nanocatalyst was compared for effective utilization. About 46.5 % of photocatalytic activity was observed without UV light irradiation within 120 minutes. The photocatalytic activity of W-Ce co-doped TiO2 to degrade atrazine further increased up to 99.1 % when the solution was irradiated under UV light. Factors like pH, time, and concentration of nanocatalyst were optimized to check the photocatalytic activity of nanocatalyst on ATZ. It was concluded that nanocatalyst showed an efficient photocatalytic degradation at pH 6 within 120 mins time interval after exposure to UV light.

“…Toxicological studies have shown that DEA has similar toxicity to its parent compound atrazine (Kumar and Singh 2016). Sánchez et al (2020) found that atrazine in soil pore water predominantly exists in the form of DEA and DIA, which accounted for 59% of the total amount of residual atrazine after a 19-day experiment, indicating that DEA has relatively high water solubility, strong polarity, and high stability. Moreover, the DEA content in the parts of plants that were above the ground was much higher than that in the parts of the root, thereby posing a potential threat to human health.…”

Desethyl-atrazine (DEA) is a metabolite of atrazine that exerts a considerable influence on the environment. In this study, tall fescue biochar was prepared by pyrolysis at 500 °C, and batch experiments were conducted to explore its effect on the adsorption behavior of DEA in red soil, brown soil, and black soil. The addition of biochar increased the equilibrium amount of DEA adsorption for the three soil types. A pseudo-second-order kinetic model most closely fit the DEA adsorption kinetics of the three soils with and without biochar, with a determination coefficient (R2) of 0.962 to 0.999. The isothermal DEA adsorption process of soils with and without biochar was optimally described by the Freundlich and Langmuir isothermal adsorption models with R2 values of 0.98 and above. The DEA adsorption process in the pristine soil involved an exothermic reaction, which became an endothermic reaction after the addition of biochar. Partitioning was dominant throughout the entire DEA adsorption process of the three pristine soils. Conversely, in soils with biochar, surface adsorption represented a greater contribution toward DEA adsorption under conditions of low equilibrium concentration. The overall results revealed that the tall fescue biochar was an effective adsorbent for DEA polluted soil.
