Summary: One of the biggest challenges of the modern world is the antibiotic pollution in water resources due to the lack of effective removal techniques in conventional wastewater treatment processes. However, commercially available adsorbents with the desired properties for selective removal of specific antibiotic classes are rare. In this study, a CNS@ZIF67 heterostructure derived adsorbent was developed for the pH-dependent removal of ciprofloxacin (CIP). The adsorbent demonstrated a high removal efficiency of 96% within 2 hours and showed interesting pH dependent adsorption behavior. It also proved to be reusable for four cycles without significant loss of removal efficiency.

Summary: In this study, a simple and eco-friendly method was developed for the removal of thiophene from gasoline using water-based silver nanoparticles. The silver nanoparticles were prepared using tannic acid as a reducing and stabilizing agent, and their adsorption efficiency was evaluated. It was found that silver nanoparticles of size 8.3 +/- 2 nm showed the highest adsorption efficiency (88.4%) for thiophene. The adsorption process followed a pseudo-second-order kinetics, and the mechanism involved the displacement of tannic acid by thiophene. This approach provides a new way to remove thiophene using aqueous silver nanoparticles.

Summary: Efficient adsorption of antibiotics from livestock wastewater is urgently needed. In this study, alkaline-modified biochar with larger surface area and pore volume was used for the adsorption of different types of antibiotics. The adsorption process was mainly determined by chemisorption and was influenced by solution pH. The study also revealed that the -OH groups on biochar surface were the dominant active sites for antibiotics adsorption. Furthermore, the biochar showed synergistic adsorption towards Zn2+/Cu2+ and antibiotics in a multi-pollutants system.

Summary: To address heavy-metal ions in wastewater, researchers synthesized boron nitride quantum dots (BNQDs) in-situ on rice straw derived cellulose nanofibers (CNFs) as a substrate. The composite system, BNQD@CNFs, had strong hydrophilic-hydrophobic interactions and a large surface area of luminescent fibers. BNQD@CNFs showed affinity for Hg(II) and successfully adsorbed it due to strong electrostatic interactions and the presence of polar B-N bonds. This composite also exhibited high potential in wastewater remediation, with a high adsorption capacity and recyclability.
