“…Figure 8B shows the maximum adsorption capacity of different materials for tetracycline. Similarly, the maximum adsorption capacity of sea urchin‐like BN for tetracycline was higher than that of SWNT, 39,40 resins, 41 and various types of BN, 18‐20,42 which was only slightly lower than the BN‐Ni reported in the literature 21 . Therefore, the prepared BN with a sea urchin‐like structure could effectively adsorb organic pollutants and had broad application value in the field of water pollution treatment.…”

Water pollution, especially caused by organic pollutants, seriously affects people's health and even threatens life. Boron nitride (BN) adsorbents with unique sea urchinlike structures were fabricated after low-temperature treatment, freeze-drying, and high-temperature calcination. Results indicated that the sea urchin-like structure was a combination of fibers spreading outward from the center to its surroundings. As the temperature difference was gradually increased in the low-temperature treatment, the diameter of the sea urchin-like structure decreased and the Brunner-Emmett-Teller surface area increased. The adsorbents showed efficient adsorption rates and excellent reusability for dyes and antibiotics. Specifically, the maximum adsorption capacities for methylene blue and tetracycline were higher than those described in most of the literature, reaching 592.37 and 369.79 mg/g, respectively. This may have be attributed to the sea urchin-like structure of the porous fibers able to trap organic pollutants in the center, which showed strong intermolecular interactions with organic pollutants, that is, π-π bond binding force and acid-base complexation. The obtained BN adsorbents with sea urchin-like structures have great applicability in areas where organic pollutant adsorption is prevalent.

Antibiotics are used widely in human and veterinary medicine, and are ubiquitous in environment matrices worldwide. Due to their consumption, excretion, and persistence, antibiotics are disseminated mostly via direct and indirect emissions such as excrements, sewage irrigation, and sludge compost and enter the soil and impact negatively the natural ecosystem of soil. Most antibiotics are amphiphilic or amphoteric and ionize. A non-polar core combined with polar functional moieties makes up numerous antibiotic molecules. Because of various molecule structures, physicochemical properties vary widely among antibiotic compounds. Sorption is an important process for the environment behaviors and fate of antibiotics in soil environment. The adsorption process has decisive role for the environmental behaviors and the ultimate fates of antibiotics in soil. Multiply physicochemical properties of antibiotics induce the large variations of their adsorption behaviors. In addition, factors of soil environment such as the pH, ionic strength, metal ions, and organic matter content also strongly impact the adsorption processes of antibiotics. Review about adsorption of antibiotics on soil can provide a fresh insight into understanding the antibiotic-soil interactions. Therefore, literatures about the adsorption mechanisms of antibiotics in soil environment and the effects of environment factors on adsorption behaviors of antibiotics in soil are reviewed and discussed systematically in this review.

“…For instance, CR in DRC may encourage its adhesion with gastric mucosa, which results in elevated gastric retention of DRC [21,22]. Some DRCs are being developed by employing ion exchange resins and antibiotics such as amoxicillin [23], cimetidine [24], tetracycline [25], etc. These DRCs have demonstrated their worth as a better approach for efficient targeting and treatment of H. pylori infections (fundus) in the stomach.…”

Objectives: This work was aimed to develop and evaluate formulations containing amoxicillin trihydrate (AMT) to confirm their therapeutic potential against Helicobacter pylori infection. Materials and Methods:A drug-resin complex (DRC) was synthesized using AMT and cholestyramine and optimized. Afterward, this optimized DRC was loaded in the chitosan microspheres (MS) possessing dual qualities (i.e., floating and mucoadhesive).Results: Floating MS were investigated for various parameters for instances, %mucoadhesion, particle size, and morphology, %drug-entrapment efficiency (%DEE), floating ability (in vitro), and drug release (in vitro) profile. Findings from optimized formulations suggested good DEE (79.65±2.13%) of drug and average particle size (106.49±4.45 μm). In addition, MS revealed decent buoyancy (78.60±3.3%) and mucoadhesion (78.25±0.14%) ability along with good floating lag-time (>20 min). On the other hand, in vitro results advocated sustained release profile of AMT for up to 24 h. As hypothesized, fluorescence (in vivo) study confirmed prolonged retention of MS in the stomach. Conclusion:MS with dual qualities can be used for attaining encouraging results (in vitro) in the treatment of infection caused by Helicobacter pylori.
