“…This behaviour can be explained as the molecule of tetracycline was not adsorbed by intercalation into the interlayer space of the adsorbent structure, but TC was adsorbed on the surface of the clay ATMa and GM [75,176]. The characteristic bands of TC are in the range of 1200-1700 cm -1 [75,[177][178][179]. On the infrared spectrum of ATMa-TC it is observed the vibration bands at 1113, 1633, 3527, 3394 and 3617 cm -1 .…”

The use of antibiotics for breeding and for humans increased considerably in recent years, as a dietary supplement to enhance animal growth. This frequent use leads to the detection of residues in water and wastewater. Thus, the emergence of new strains of bacteria resistant to these antibiotics and, can lead to incurable diseases of livestock, and can lead to a possible transmission of these strains to humans. The purpose of this work is to develop new materials based on treated Maghnia clay, activated carbon, cement, and PVA polymer, named geomaterials. These materials were intended for the containment of hazardous wastes in landfills. The removal of tetracycline from aqueous solution was tested by adsorption onto synthesised geomaterials and their mineral constituents. Adsorption kinetics revealed that tetracycline was rapidly retained by GM and ATMa. This was confirmed by the relatively short equilibrium time of 30 min. The pseudo-second-order and intraparticle models well fitted the adsorption kinetic of the TC-adsorbent studied systems. It was noticed that the adsorption kinetic passes through several mechanisms, was demonstrated by the multi-linearity on the plot of qt against the square root of t. The adsorption capacity (Qa ) of TC onto GM is pH-dependent. Indeed, Qa reaches a maximum value (Qa = 12.58 mg ∙ g–1 at a very acidic pH of 2, then the adsorbed amount decreases to reach a minimum value at pH of 8, and for basic pHsQa increases up to 10 mg ∙ g–1.

“…Most of these techniques are known for high execution expenses or less ability to accomplish respectable water quality, except for adsorption. Adsorption process has shown good performance in water decontamination against different pollutants, e.g., antibiotics (Maged et al 2020 ) and heavy metals (Abu-Danso et al 2020 ). One of the advantages of adsorption is the ability to scale up the process, without producing any by-product in the environment during treatment.…”

“…Bentonite is an inorganic 2:1 type clay mineral, which is mainly constituted of montmorillonite (Maged et al 2020 ). Due to the excellent sorption, physical and chemical properties of bentonite (i.e., CEC, porosity, particle size, and surface area), bentonite is considered as the best candidate for sorption of different kinds of emerging pollutants (Genç and Dogan 2015 ).…”

The presence of emerging pollutants such as hazardous chemicals, pharmaceuticals, pesticides, and endocrine-disrupting chemicals in water sources is a serious concern to the environment and human health. Thus, this study focused on exploring the interaction mechanisms between ciprofloxacin (CIP) (antibiotic) and clay (a low-cost adsorbent) during sorption process. Acid activation technique was opted for modifying natural bentonite (NB) to enhance the adsorptive removal of CIP from water. The BET surface area analysis revealed that acid-activated bentonite (AAB) possessed more than two fold higher surface area as compared to NB. Combining pH zpc measurements, effect of solution pH and CIP speciation revealed that CIP sorption onto bentonite is highly dependent on solution pH. Kinetic studies confirmed that CIP sorption mechanism was chemisorption which included ion-exchange and surface complexation mechanisms. The mechanism of CIP sorption onto AAB was successfully explored with the assistance of characterization techniques. Maximal monolayer sorption capacity of AAB was found to be 305.20 mg/g, compared to 126.56 mg/g for NB. Reusability studies demonstrated that AAB could be reused successfully up to 5 cycles. Furthermore, column studies showed satisfactory results confirming that AAB can be successfully used in continuous mode for practical applications.

“…In China, the use of antibiotics for livestock and medicines was about 162,000 tons in 2013, compared with 150 times the consumption of antibiotics in the UK and 10 times that of the US (Wang et al, 2017). Tetracyclines, include tetracycline (TC), chlortetracycline (CTC), oxytetracycline (OTC) and so on, are broad-spectrum bacteriostatic compounds and widely used due to their favorable properties such as low cost and high antimicrobial activity (Maged et al, 2020), and also as veterinary drugs to prevent and treat a variety of animal infectious diseases or as feed additives to promote animal growth (Dai et al, 2020). According to the survey, tetracyclines are the second most commonly used antibiotics in the world (Li et al, 2020), and CTC and OTC are two of the ten growth promoters approved in the United States (Jeong et al, 2010).…”

Tetracyclines are frequently detected in water bodies due to their widespread use in aquaculture and animal husbandry. A hydroponic experiment was conducted to explore the phytotoxic effects of Vallisneria natans (Lour.) Hare exposed to various concentrations of chlortetracycline (CTC) and oxytetracycline (OTC) (0, 0.1, 1, 10, 30, 50 and 100 mg/L) for 7 days (7 D) and 14 days (14 D), respectively. The results showed that similar to OTC treatment for 7 D, the relative growth rates (RGR) and catalase (CAT) activity of V. natans , after 7 D of CTC exposure, decreased signi cantly at 10 mg/L and 30 mg/L, respectively. The content of soluble protein notably decreased when CTC ≥ 10mg/L and OTC ≥ 30mg/L. The hydrogen peroxide (H 2 O 2 ) content was signi cantly stimulated when OTC ≥ 10mg/L, while it hardly changed when exposed to CTC. After 14 D, the malondialdehyde (MDA) and H 2 O 2 contents of V. natans were signi cantly higher than those of the control group under high concentration of OTC (≥ 30mg/L), but they didn't change signi cantly under high concentration of CTC. The activity of polyphenol oxidase (PPO), under CTC treatment after 14 D, showed rst a signi cant increase then decrease, the maximum value (125% of the control) was notice at 10 mg/L CTC, while it remained unchanged when exposed to OTC. The soluble protein content signi cantly decreased at 10 mg/L CTC and 0.1 mg/L OTC, respectively. The RGR, CAT and peroxidase (POD) activities, similar to OTC treatment after 14 D, decreased evidently when CTC was 10 mg/L, 30 mg/L and 0.1 mg/L, respectively. CTC and OTC harm the chlorophyll content of V. natans after 14 D, and the reduction of chlorophyll a and carotenoid were more pronounced than chlorophyll b. The results suggest that CTC and OTC both have negative effect on the growth of V. natans , and OTC can cause oxidative damage in V. natans but CTC harm the metabolism process without inducing oxidative damage. Overall, the toxicity of OTC to V. natans is stronger than that of CTC.
