“…Regardless of the feedstock used, the adsorption of tetracycline (TC) was more effective onto BCs produced at higher temperatures, as compared with analogous materials obtained at lower temperatures. This trend was reported for BCs derived from rice straw [129] (an increase from 300 °C to 700 °C enhanced TC adsorption by 250%), waste Auricularia auricula dregs (an increase from 300 °C to 700 °C enhanced TC adsorption by 65%) [130], pinewood (an increase from 600 °C to 800 °C enhanced TC adsorption by 56%) [133], or swine manure (an increase from 400 °C to 600 °C enhanced TC adsorption by 25%) [132]. This was associated with an increase in the porosity parameters (SBET, Vp) of the BC as a result of pyrolysis at higher temperature and with the TC adsorption mechanism onto the BC.…”

“…BCs produced at a higher temperature are usually characterized by higher hydrophobicity, aromaticity, pH values, as well as lower polarity [127,128]. Research reveals [129][130][131][132] that increasing pyrolysis temperature promotes the higher adsorption capacity of BCs toward various antibiotics.…”

“…At pH < pHPZC (pH at point of zero charge), the BC surface is positively charged, whereas at pH > pHPZC, it is negatively charged. TC, on the other hand, is an amphoteric molecule with three pKa values, i.e., at 3.3 < pH > 9.7, it has a positive or negative charge, whereas at pH in the range of 3.3-7.7, the drug is a neutral molecule and does not interact with the BC surface through electrostatic attraction/repulsion [130]. Similar results were obtained for ciprofloxacin (CIP) with respect to Astragalus mongholicus-derived BCs.…”

Antibiotic contamination and the spread of antimicrobial resistant bacteria are global environmental issues. Given the growing consumption of antibiotics, it is crucial to reduce their presence in the environment. Adsorption is one of the most efficient methods for removing contaminants from water and wastewater. For this process to be effective, it is of key importance to identify adsorption mechanisms that allow an efficient and selective adsorbent to be chosen.Carbon-based materials (including activated carbon, biochar and black carbon) are typically used for the adsorptive removal of antibiotics. To enhance the efficiency of adsorption of pharmaceuticals, engineered biochars (physically, chemically and biologically modified biochar) and their composites have attracted increasing interests. Biochar-based sorbents can be produced from various feedstocks, including waste products. The use of "green", low cost or sustainable biochar for contaminant sorption yields economic and environmental benefits.Moreover, this is in line with global trends in creating a circular economy and sustainable development. This paper collates the most recent data on the consumption of antibiotics, their related environmental contamination, and their removal using biochar-based materials. Special attention is paid to the newly emerging approaches of biochar modification and biochar composites in relation to the antibiotic removal from water.

“…Consequently, it is expected that there are other mechanisms that dominate the adsorption process such as; Pore filling effects since the length, width and height of the three-dimensional TC molecules are 1.23, 0.84 and 0.67 nm, respectively, while the average pore size of the microbeads is 2.145 nm. So, the pores of the microbeads are loose enough to penetrate the TC molecules 76 . Besides, π-π interaction between the aromatic rings in MIL-125(Ti)/MIL-53(Fe)/CNT@Alg (π- electron donor) and TC molecules (π- electron acceptor) 7 , 43 .…”

In this investigation, we aimed to fabricate easy separable composite microbeads for efficient adsorption of tetracycline (TC) drug. MIL-125(Ti)/MIL-53(Fe) binary metal organic framework (MOF) was synthetized and incorporated with carbon nanotube (CNT) into alginate (Alg) microbeads to form MIL-125(Ti)/MIL-53(Fe)/CNT@Alg composite microbeads. Various tools including FTIR, XRD, SEM, BET, Zeta potential and XPS were applied to characterize the composite microbeads. It was found that the specific surface area of MIL-125(Ti)/MIL-53(Fe)/CNT@Alg microbeads was 273.77 m2/g. The results revealed that the adsorption of TC augmented with rising CNT proportion up to 15 wt% in the microbeads matrix. In addition, the adsorption process followed the pseudo-second-order and well-fitted to Freundlich and Langmuir models with a maximum adsorption capacity of 294.12 mg/g at 25 ◦C and pH 6. Furthermore, thermodynamic study clarified that the TC adsorption process was endothermic, random and spontaneous. Besides, reusability test signified that MIL-125(Ti)/MIL-53(Fe)/CNT@Alg composite microbeads retained superb adsorption properties for six consecutive cycles, emphasizing its potentiality for removing of pharmaceutical residues.

“…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.
