“…[50] It was expected that non-ideal multilayer adsorption was achieved on the heterogeneous CuBi 2 O 4 /BiOBr heterojunction surface. [51] Additionally, the increased Freundlich adsorption constant (k F ) value clarified that the adsorption capacity of CuBi 2 O 4 /BiOBr was improved along with the increased temperature, which was consistent with the result in Figure S12. Meanwhile, a larger value of 1/n implied a stronger adsorption capacity at higher temperature.…”

A novel direct Z‐scheme CuBi2O4/BiOBr heterostructural photocatalyst was developed aiming to modulate the adsorption ability and photocatalytic degradation performance toward antibiotics. Tetracycline as the model antibiotics was found to show pH value and temperature dependent adsorption capacity over CuBi2O4/BiOBr. The adsorption process was fitted to Pseudo‐second‐order and Elovich kinetic models and adsorption isotherm was followed Freundich isotherm model. Junction of CuBi2O4 and BiOBr can modulate the surface feature and interfacial interactions, leading to direct Z‐scheme charge kinetics for improved photocatalytic activity. The adsorptive capability and photocatalytic performance of CuBi2O4/BiOBr heterojunction showed great improvement in comparison with pristine CuBi2O4 and BiOBr. The mineralization process and intermediates for tetracycline degradation were identified by total organic carbon analysis and liquid chromatograph‐tandem mass spectrometry. Plausible transformation pathway and photocatalytic mechanism were proposed. Radical trapping experiments indicated that photogenerated holes and ⋅O2−active species played crucial roles in photocatalytic tetracycline decomposition.

“…It can be seen that the theoretical saturated adsorption amount increased with temperature raised, which was consistent with the experimental data. The maximum theoretical saturated adsorption capacity at 323 K was 442.5 mg•g −1 , which is better than ZIF-8 [33] and biochar materials reported in the literatures [26,27,30].…”

“…However, the lower utilization rate causes that more than 70% of tetracycline would be excreted in urine and feces of humans and animals and released into the environment [15]. As far as we know, various adsorption materials have been developed to remove TC from aqueous solution, such as clay minerals [19][20][21], zeolites composites [22,23], graphene oxide (GO) [24], multi-walled carbon nanotubes (MWC-NTs) [25], biochar [26][27][28][29][30], covalent-organic frameworks (COFs) [31], metal-organic frameworks (MOFs) [32][33][34][35][36] and their composites [37][38][39][40][41]. Among these adsorbent materials, MOFs, composed of organic linkers and metallic clusters, are a new class of porous materials.…”

MOF-818, a mesoporous cage metal-organic framework, was investigated for the removal of tetracycline hydrochloride (TC) from aqueous environment. The product was characterized by XRD, BET, FESEM, FT-IR, XPS and TGA. The influence of different parameters such as solution pH, contact time, temperature, adsorption dosage, initial TC concentration on the adsorption capacity was investigated. The as-prepared MOF-818 showed rapid removal of TC and with maximum saturated adsorption capacity calculated to be 442.5 mg g −1 at pH 3.32, 323 K. The adsorption isotherms were fitted by Langmuir, and Freundlich models. The kinetic data was analyzed by pseudo-first-order, pseudo-second-order, and intraparticle diffusion models. The TC adsorption process followed pseudo-second-order kinetics and best fitted the Langmuir adsorption model. The thermodynamic data showed that the adsorption was a spontaneous and endothermic reaction. A mechanism for TC adsorption was proposed and the chemisorption and π-π interaction was believed to direct the interaction between MOF-818 and TC molecules.

“…Tetracycline (TC) was an amphoteric substance with different ionizable groups on the molecule surface at different pH values (Figure 2a insert). The dominated TC (H 2 TC) species were H 3 TC + at pH < 3.4, H 2 TC at pH of 3.4-7.6, HTC − at pH of 7.6-9.0, and TC 2− at pH > 9 [13]. The pH pzc of ZBAC was 8.3 (Figure 2b).…”

The bands at 1118, 1086, and 880 cm −1 were related to C-N stretching vibrations, C-H symmetric deformation vibrations, and N-H deformation vibrations [13]. Comparing the spectroscopy before and after adsorption, the band at 1086 cm −1 was weakened after adsorption and new bands of 880 cm −1 appeared.…”

Adsorption and desorption behaviors of tetracycline hydrochloride by activated carbon-based adsorbents derived from sugar cane bagasse modified with ZnCl 2 were investigated. The activated carbon was tested by SEM, EDX, BET, XRD, FTIR, and XPS. This activated carbon exhibited a high BET surface area of 831 m 2 g −1 with the average pore diameter and pore volume reaching 2.52 nm and 0.45 m 3 g −1 , respectively. The batch experimental results can be described by Freundlich equation, pseudo-second-order kinetics, and the intraparticle diffusion model, while the maximum adsorption capacity reached 239.6 mg g −1 under 318 K. The effects of flow rate, bed height, initial concentration, and temperature were studied in fixed bed adsorption experiments, and adsorption data were fitted with six dynamic adsorption models. The results of characterizations and the batch experiments were analyzed to study the adsorption and desorption mechanisms. Tetracycline hydrochloride and activated carbon were bonded together by π-π interactions and cation-π bonds. Ethanol was used as an eluent which bonded with 10 hydrogen bond acceptors on tetracycline hydrochloride to form a complex by hydrogen bonding to achieve recycling.Molecules 2019, 24, 4534 2 of 17 has numerous -OH groups, some of which remain in the pyrolysis, while other parts forms new chemically-reactive oxygen functional groups [6]. AC contains not only a benzene ring but also many chemically reactive oxygen functional groups (-OH, -COOH, etc.), which can be used for chemical modification [7]. The -NH 2 group in the TCH can form a π-π interaction and a cation-π bond with the benzene ring on the ZnCl 2 activated bagasse-based activated carbon (ZBAC). During the pyrolysis process, cellulose and hemicellulose in bagasse (about 50 wt% cellulose and 25 wt% hemicellulose) are decomposed at 202 • C to produce levoglucosan (LGA) and anhydrosugar polymers. The isomerization reaction occurs after LGA dehydration which forms other anhydrosugars and furans [8]. The pyrolysis product is polymerized to form activated carbon at 600 • C. The activated carbon produced by direct the pyrolysis of bagasse has a small specific surface area (S BET was about 376.08 m 2 g −1 ), and ZnCl 2 helps to form more porous structures during pyrolysis (S BET was about 831.23 m 2 g −1 ) because ZnCl 2 catalyzes the Scholl condensation reaction during pyrolysis. The above-mentioned macromolecular polycyclic compounds in bagasse form porous structures during pyrolysis at high temperatures [9].However, how activated carbon's effect on the fate of tetracycline hydrochloride (TCH) in water has become a question demanding a quick solution, and few reports have paid attention to the adsorption and desorption behavior and mechanism. Desorption behavior influences not only the fate of TCH in the environment, which is still a primary concern, but also the efficient recycling of the adsorbent [10]. The structure-activity relationship of adsorbents plays a significant component in the adsorption and desorption process....
