In this study, CuO-Co3O4 co-modified porous boron nitride fibers were prepared as adsorbents for the removal of tetracycline antibiotics in aqueous environment. The results showed that the prepared adsorbent had high removal efficiency and good renewable recycling performance.
The presence of antibiotic contaminants in aqueous environment already poses significant risks to ecological sustainability, biodiversity and human public health and safety. Therefore, it is urgent to develop practical water pollution control technologies and new materials. Here, we prepared CuO-Co3O4 co-modified porous boron nitride fibers (P-BNFs) for the adsorption and removal of tetracycline antibiotics (TCs) in aqueous environment. The prepared adsorbents were characterized by XRD, FTIR, XPS, SEM, TEM and BET, and the adsorption behavior was explored by batch experiments. The results show that the removal percentage for doxycycline (DC) reaches 98.68 %, which was much higher than that of P-BNFs, and the modification results of P-BNFs with CuO or Co3O4 alone. After five regeneration cycles, the removal rate of DC by CuO-Co3O4/P-BNFs was still as high as 89.33 %. This is promising and indicates that the prepared CuO-Co3O4/P-BNFs adsorbent has good renewable recycling performance and practical application prospects.
