“…On the other hand, benzotriazoles are stable to heat, ultraviolet radiation and chemical or bacterial attack but these characteristics makes them persistent xenobiotics under environmental conditions. They have also been identified as carcinogenic substances and have been shown to induce toxic responses in fish, invertebrates and marine and soil bacteria at low concentrations [52,53]. As compared to these organic inhibitors, polymeric materials are not yet as widely used.…”

With the intention of taking care of the environment and human health, the development of alternative eco-friendly methods to inhibit metal corrosion is intensively encouraged. In previous works we showed that some phytocompounds components of essential oils such as carvacrol (Carv) and thymol (TOH) are able to be electropolymerized on metals and they seem to be promissory for this purpose. The aim this paper is to investigate if the biocompatibility of copper covered by coatings formed by electropolymerization of Carv and TOH (polyCarv and polyTOH) is related with the potential selected for the electropolymerization process. Potentiostatic perturbations at different potentials, AFM images, ATR-FTIR spectroscopy and measurements of copper ions release provided suitable information to make a detailed analysis of different stages of the electropolymerization process that leads to polyCarv and polyTOH layers on copper surface. The change of the characteristics of the coatings over time was evaluated after several polymerization periods and current transients were interpreted by using nucleation and growth models. Results showed interesting changes in the polymerization process with the electrochemical perturbation, nature of the isomer, and time of the treatment. The treatment that provides the most protective, transparent and homogeneous layer, that strongly increased the biocompatibility of Cu could be selected: electropolymerization of Carv at 0.4V. Results highlight the importance of the detailed study of the evolution of the electropolymerization processes to select the best ecofriendly condition due the high impact of potential perturbation and polarization time on the biocompatibility of the resulting polymeric layer-copper system.

“…The phytoremediation of benzotriazoles (log K ow ¼ 1.44) by sunflowers (Helianthus annuus) was studied and benzotriazoles were actively taken up and transformed by the plants when the concentration of benzotriazoles was lower than the toxic threshold of 100 mg/L (Castro, Davis, & Erickson, 2003;Castro et al, 2004). As a follow up the application of horizontal flow CWs planted with Phragmites spp., Typha latifolia, and Schloenoplectus lacustris for the removal of benzotriazoles was studied and an increased removal in the planted CWs was observed (Castro, Davis, & Erickson, 2005). In contrast, the removal of benzotriazole in unplanted vertical flow CWs and similar CWs planted with Phalaris arundinacea var.…”

Large volumes of freshwater are used globally for cooling towers. The reuse of discharged cooling tower water in cooling towers itself could mitigate freshwater scarcity problems. Prior to its reuse, the cooling tower blowdown has to be desalinated. However, physicochemical desalination techniques are hampered by conditioning chemicals (CC) that are added to the cooling tower water circuit to prevent corrosion, mineral scaling, and biofouling and can damage physicochemical desalination equipment. The potential of constructed wetlands (CWs) for the cost-effective removal of these CC prior to desalination is discussed in this review. The characteristics of CWs that determine their suitability for the removal of CC from cooling tower blowdown are elucidated, such as multiple removal pathways working simultaneously. In addition, specific challenges for the design of a constructed wetland for cooling tower blowdown treatment are reviewed, such as configuration options, the toxicity of CC, and the formation and removal of harmful byproducts.

“…In the last decade, benzotriazoles (BTAs) are extensively used in industrial products such as polymer stabilizers, airport deicers/anti-Icers, anti-corrosion chemicals, and even dishwashing detergents 1 . The annual production of BTA and its related derivatives has been reported to be in the range of 9000 tons/year worldwide 2 .…”

In this paper, the removal of benzotriazole (BTA) was investigated by a Photo-Fenton process using nano zero valent iron (NZVI) and optimization by response surface methodology based on Box-Behnken method. Effect of operating parameters affecting removal effi ciency such as H 2 O 2 , NZVI, and BTA concentrations as well as pH was studied. All the experiments were performed in the presence of ultraviolet radiation. Predicted levels and BTA removal were found to be in good agreement with the experimental levels (R 2 = 0. 9500). The optimal parameters were determined at 60 min reaction time, 15 mg L -1 BTA, 0.10 g L -1 NZVI, and 1.5 mmol L -1 H 2 O 2 for Photo--Fenton-like reaction. NZVI was characterized using X-ray diffraction (XRD), transmission electron microscope (TEM) images, and scanning electron microscope (SEM) analysis.
