“…Besides that, a strong absorption band at 1723.04 cm −1 , 1720.78 cm −1, and 1725.04 cm −1 of MIP (MAA), MIP (AAm), and MIP (2VP) interpreted the presence of C=O stretching vibrations, [41,42] which confirmed the successful incorporation of the carbonyl group from EGDMA cross‐linker in the MIPs structure. This peak intensity varied among different MIPs, suggesting the usage of different functional monomers such as MAA, AAm, and 2VP.…”

“…The peaks at 1056.75 cm −1 and 1055.09 cm −1 correspond to the C−N stretching vibration of the 2VP functional monomer in both MIP (2VP) and NIP (2VP), respectively. MIP (2VP) and NIP (2VP) had weak peaks at 950.55 cm −1 and 950.17 cm −1 , respectively, indicating the presence of =C−H bending vibration of the vinyl group [42] in 2VP functional monomer and EGDMA cross‐linker. Additionally, MIP (2VP) had a medium peak at 881.06 cm −1 while NIP (2VP) had a peak at 877.81 cm −1 which revealed the C=C bending vibrations of alkene group in 2VP functional monomer and EGDMA cross‐linker.…”

“…These peaks also display the incorporation of MAA and 2VP as functional monomers in their respective MIPs. The peak at 1388.35 cm −1 may also show the O−H bending vibration in the carboxylic acid group [42] of MAA while the peak at 1390.53 cm −1 may signify the C−N stretching in the aromatic ring of 2VP.…”

Atrazine (ATZ) is a widely used triazine herbicide in agriculture, however, it negatively affects the environment and human health. Therefore, a molecularly imprinted polymer (MIP) was employed for the selective removal of ATZ. In this study, MIPs were produced by precipitation polymerization using ATZ as the target molecule, methacrylic acid (MAA), acrylamide (AAm), and 2‐vinylpyridine (2VP) as functional monomers and ethylene glycol dimethacrylate (EGDMA) as cross‐linker, respectively. MIP characterizations were performed using Fourier Infrared spectroscopy (FTIR) and Field Emission Electron Microscopy (FESEM). The batch binding study revealed that MIP (2VP) exhibited the highest rebinding efficiency (88.44 %) among the MIPs. Furthermore, MIP (2VP) was analyzed by Energy‐Dispersive X‐ray spectroscopy (EDX), Brunauer‐Emmett‐Teller (BET) analysis, and thermogravimetric analysis (TGA). Adsorption studies revealed that the optimum conditions for maximum adsorption efficiency were 8 ppm ATZ solution at pH 7, using 0.3 g of MIP (2VP). MIP (2VP) demonstrated higher selectivity towards ATZ than the Ametryn (AME) a competitive interferent, with a relative selectivity coefficient of 2.77. MIP (2VP) successfully removed ATZ from distilled water (95.39 %), tap water (88.16 %) and river water (86.75 %). These findings contributed for the development of MIP for the removal of ATZ, which would be helpful in the protection of ecosystem and human health in future.

“…In addition, an intense peak at 1550 cm −1 can be observed in spectrum D (experiment performed only with zeolite), while for spectra B and C (samples of bacteria supported on zeolite), only a weak signal is observed in this region. This peak can be attributed to the N-H bending of primary amine present in atrazine molecules[68]. These observations may be an indication that atrazine can be degraded by the bacterial biofilm, which explains that the peak at 1550 cm −1 has a lower signal in comparison to that observed for the zeolite without bacterial biofilm.…”

Performance of a Combined Bacteria/Zeolite Permeable Barrier on the Rehabilitation of Wastewater Containing Atrazine and Heavy Metals

Several chemicals, such as pesticides and heavy metals, are frequently encountered together in environment matrices, becoming a priority concerning the prevention of their emissions, as well as their removal from the environment. In this sense, this work aimed to evaluate the effectiveness of a permeable biosorbent bio-barrier reactor (PBR) on the removal of atrazine and heavy metals (copper and zinc) from aqueous solutions. The permeable bio-barrier was built with a bacterial biofilm of R. viscosum supported on 13X zeolite. One of the aims of this work is the investigation of the toxic effects of atrazine, copper and zinc on the bacterial growth, as well as the assessment of their ability to adapt to repeated exposure to contaminants and to degrade atrazine. The growth of R. viscosum was not affected by concentrations of atrazine bellow 7 mg/L. However, copper and zinc in binary solutions were able to inhibit the growth of bacteria for all the concentrations tested (5 to 40 mg/L). The pre-acclimation of the bacteria to the contaminants allowed for an increase of 50% of the bacterial growth. Biodegradation tests showed that 35% of atrazine was removed/degraded, revealing that this herbicide is a recalcitrant compound that is hard to degrade by pure cultures. The development of a PBR with R. viscosum supported on zeolite was successfully performed and the removal rates were 85% for copper, 95% for zinc and 25% for atrazine, showing the potential of the sustainable and low-cost technology herein proposed.
