“…Synthetic reactive dyes released from the textile industry have very serious implications for water ecosystems and humans [ 3 ]. Similarly, pharmaceutical compounds released from domestic and industrial wastewater in small concentrations pose a significant challenge to the environment due to their bioactive nature [ 4 ]. Laccase catalyzes the redox-mediated degradation of various pollutants.…”

“…Textile dyes released from textile industries into the water lead to several hazards to the environment, mainly due to their recalcitrant and toxic nature [ 3 ]. In recent decades, emerging pharmaceutical contaminants released in very small concentrations caused a significant challenge to the environment, mainly due to their bioactive nature and the development of antibiotic resistance in the microbes [ 4 ]. The pharmaceutical compounds caused the development of antibiotic resistance in the microbes, hence taking the entire world into a serious health challenge [ 5 ].…”

This study focuses on the development of a nanosupport based on halloysite nanotubes (HNTs), Fe3O4 nanoparticles (NPs), and thiolated chitosan (CTs) for laccase immobilization. First, HNTs were modified with Fe3O4 NPs (HNTs-Fe3O4) by the coprecipitation method. Then, the HNTs-Fe3O4 surface was tuned with the CTs (HNTs-Fe3O4-CTs) by a simple refluxing method. Finally, the HNTs- Fe3O4-CTs surface was thiolated (-SH) (denoted as; HNTs- Fe3O4-CTs-SH) by using the reactive NHS-ester reaction. The thiol-modified HNTs (HNTs- Fe3O4-CTs-SH) were characterized by FE-SEM, HR-TEM, XPS, XRD, FT-IR, and VSM analyses. The HNTs-Fe3O4-CTs-SH was applied for the laccase immobilization. It gave excellent immobilization of laccase with 100% activity recovery and 144 mg/g laccase loading capacity. The immobilized laccase on HNTs-Fe3O4-CTs-SH (HNTs-Fe3O4-CTs-S-S-Laccase) exhibited enhanced biocatalytic performance with improved thermal, storage, and pH stabilities. HNTs-Fe3O4-CTs-S-S-Laccase gave outstanding repeated cycle capability, at the end of the 15th cycle, it kept 61% of the laccase activity. Furthermore, HNTs-Fe3O4-CTs-S-S-Laccase was applied for redox-mediated removal of textile dye DR80 and pharmaceutical compound ampicillin. The obtained result marked the potential of the HNTs-Fe3O4-CTs-S-S-Laccase for the removal of hazardous pollutants. This nanosupport is based on clay mineral HNTs, made from low-cost biopolymer CTs, super-magnetic in nature, and can be applied in laccase-based decontamination of environmental pollutants. This study also gave excellent material HNTs-Fe3O4-CTs-SH for other enzyme immobilization processes.

“…Tertiary treatment takes place in exceptional cases, only when additional water purification is required; for example, the disinfection or removal of specific nutrients or toxic compounds [35]. For this purpose, different chemical and physical methods are used: chlorination (most often), ozonation, UV treatment, membrane filtration, adsorption processes [35,43].…”

Application of TiO2-Based Photocatalysts to Antibiotics Degradation: Cases of Sulfamethoxazole, Trimethoprim and Ciprofloxacin

2021

View full text Add to dashboard Cite

The extensive application of antibiotics in human and veterinary medicine has led to their widespread occurrence in a natural aquatic environment. Global health crisis is associated with the fast development of antimicrobial resistance, as more and more infectious diseases cannot be treated more than once. Sulfamethoxazole, trimethoprim and ciprofloxacin are the most commonly detected antibiotics in water systems worldwide. The persistent and toxic nature of these antibiotics makes their elimination by conventional treatment methods at wastewater treatment plants almost impossible. The application of advanced oxidation processes and heterogeneous photocatalysis over TiO2-based materials is a promising solution. This highly efficient technology has the potential to be sustainable, cost-efficient and energy-efficient. A comprehensive review on the application of various TiO2-based photocatalysts for the degradation of sulfamethoxazole, trimethoprim and ciprofloxacin is focused on highlighting their photocatalytic performance under various reaction conditions (different amounts of pollutant and photocatalyst, pH, light source, reaction media, presence of inorganic ions, natural organic matter, oxidants). Mineralization efficiency and ecotoxicity of final products have been also considered. Further research needs have been presented based on the literature findings. Among them, design and development of highly efficient under sunlight, stable, recyclable and cost-effective TiO2-based materials; usage of real wastewaters for photocatalytic tests; and compulsory assessment of products ecotoxicity are the most important research tasks in order to meet requirements for industrial application.

Recent Advances on the Aqueous Phase Adsorption of Carbamazepine

et al. 2022

View full text Add to dashboard Cite

Carbamazepine (CBZ) is a pharmaceutical compound used in medical practice. Due to the ecotoxicological risk of its presence in the aqueous environment, researchers have been investigating its removal by adsorption technique. The aim of this study is to review the works done on the removal of CBZ from water by adsorption. Carbon‐based materials were the best types of adsorbent for CBZ uptake (> 200 mg g−1). Molecularly imprinted polymer (MIP) and carbon nanotubes (CNTs) showed especially good adsorption capacities. The key mechanisms of CBZ adsorption were π‐π interaction, electrostatic interactions, hydrogen‐bonding and hydrophobic interactions. Classical equilibrium isotherm models like Langmuir and Freundlich were always best‐fits and kinetics modelling was best‐fit to the pseudo‐second order model. The thermodynamics modelling of CBZ adsorption showed it was spontaneous and endothermic for most adsorbents. Methanol and acetone were especially effective for the desorption of CBZ from adsorbents and can achieve > 90 % removal even after 4–5 cycles. CBZ competes favorably in adsorption systems with other pharmaceutical species due to the advantages of the hydrophobic effect and molecular size.
