“…Subsequently, F-C was compounded with gelatin. Gelatin has favorable properties for the production of adsorbent composites due to its excellent gel-forming ability, low procurement cost, biodegradability and hydrophobicity [ 21 ]. Then, we used glutaraldehyde as a crosslinking agent to crosslink the molecular chains of gelatin to enhance their mechanical structure.…”

A novel gelatin-based functionalized carbon nanotubes@metal–organic framework (F-CNTs@MOF@Gel) adsorbent was prepared by the green and simple method for the adsorption of methylene blue (MB). Cu-BTC (also known as HKUST-1) was selected as the MOF type. F-CNTs@Cu-BTC particles were fixed by gelatin, thus avoiding the secondary pollution of carbon nanomaterial particles to the environment. CNTs were used as the connecting skeleton to make more effective adsorption sites exposed on the surface of the internal pore structure of the adsorbent. In this paper, scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (XRD), thermogravimetry (TGA) and BET analysis methods were used to characterize the new adsorbent. The effects of time, temperature, pH, dosage and initial concentration on the adsorption process were investigated by batch adsorption experiments. The adsorption mechanism was further analyzed by several commonly used kinetic and isotherm models, and the reliability of several fitting models was evaluated by the Akaike information criterion (AIC), Bayesian information criterion (BIC) and Hannan information criterion (HIC). After five regeneration experiments, the adsorbent still had 61.23% adsorption capacity. In general, the new adsorbent studied in this paper has an optimistic application prospect.

“…They are mostly organic and highly polar contaminants, such as drugs, hormones, herbicides, pesticides, dyes, and toxic metals, among other compounds 2 . Due to the low biodegradability of these contaminants, they are not entirely removed in waste water treatment plants 2–7 and are often found in surface water, groundwater, and even drinking water at concentrations of nanograms to micrograms per liter 8 . Therefore, it is necessary to study and improve the techniques to remove those contaminants.…”

BACKGROUND Drugs and pesticides are emerging contaminants, and their presence in surface and groundwater have been increasing. Therefore, this work aims to study the modification of natural zeolite to remove these contaminants from water. RESULTS Among the modifications carried out, hydrothermal treatment in the presence of surfactant (CTAB) was highlighted. The hydrothermal treatment with surfactant provided a structural rearrangement. As a result, the zeolite became more hydrophobic, with a smaller specific area and a more significant amount of mesopores and macropores. Changes in textural and chemical characteristics resulted in a significant increase in the removal of the evaluated pesticides and drugs. In order to evaluate the potential of zeolites to remove emerging contaminants under conditions closer to reality, the modified samples were evaluated in the adsorption process of simulated contaminated water. The maximum adsorption capacities obtained were 28.24, 3.07, and 20.06 mg g−1 for 2,4‐D, diuron, and diclofenac, respectively, using HT‐H2O_CTAB under conditions closer to real water treatment (30 °C and natural pH of the solution). CONCLUSION The results demonstrate that hydrothermal modification with CTAB is a promising ‘chimie douce’ technique to use natural zeolites to remove emerging contaminants. © 2022 Society of Chemical Industry (SCI).

“…However, the massive use of these antivirals causes the contamination of various environmental matrices (Tlili et al 2016 ; Ben Sghaier et al 2017 ; Gupta et al 2021 ) and impacts the functioning of the ecosystem which leads to risks for human and animal health (Yang et al 2017 ; Rigueto et al 2021 ). An overview of management practices and effective treatment processes for removing emerging contaminants from hospital wastewater was reported (Khan et al 2021 ).…”

Cuttlefish bone powder as an efficient solid-phase extraction sorbent of anti-SARS-CoV-2 drugs in environmental water

Many antiviral drugs were developed to counteract coronavirus disease, 2019 (COVID-19) with severe acute respiratory syndrome. Therefore, the scientific community's efforts have focused on the detection and quantification of antiviral compounds currently being tested for COVID-19 treatment. Cuttlefish bone powder (CFBP) has been used for the first time as solid-phase extraction (SPE) sorbent for the extraction of SARS CoV-2 antiviral drugs (chloroquine, ritonavir and indomethacin) from water samples. An effective and sensitive method was developed by combining SPE and liquid chromatography- UV detection (LC-UV). An experimental design was applied for the optimization of extraction process. Experimental variables were optimized using Doehlert matrix. The developed method included 50 mg of CFBP sorbent, 20 mL of water sample at pH = 9 and 5 mL of ACN/KH 2 PO 4 buffer solution (80:20, v/v) in the elution step. For validation of the method, selectivity, linearity precision, and sensitivity were evaluated. Extraction recovery percentage of all Sars cov-2 antivirals were above 98.2%. The detection and quantification limits were between 0.1 and 0.5 µg L −1 and 0.6 and 2 µg L −1 , respectively. The current study suggested that CFBP has the application potential for the enhanced SPE of SARS CoV-2 antiviral drugs from water samples.
