Antibiotic contamination in water has been an increasing global concern, and how to effectively remove antibiotics (e.g., oxytetracycline [OTC] hydrochloride) from wastewater becomes imperative. In this study, the biochar derived from an invasive plant (Mikania micrantha Kunth) was synthesized with Zn/Fe- layered double hydroxide (LDH) by co-precipitation method (ZnFe-LDH/MBC) to remove OTC from water. ZnFe-LDH/MBC posed the highest OTC removal performance of 426.61 mg/g. ZnFe-LDH/MBC exhibited stability and efficiency in OTC adsorption at different pH levels and under interfering conditions with co-existing ions, as well as outstanding regeneration capabilities during adsorption-desorption cycles. Furthermore, the removal of OTC by ZnFe-LDH/MBC was mediated by several processes including pore filling, hydrogen bonding force, electrostatic interaction, π-π interaction, as well as complexation. Consequently, ZnFe-LDH/MBC has excellent potential for the purification of OTC pollutants that is low-cost, efficient, and environmentally friendly.

... The efficiency of the MgAl-LDH and MgAl-LDH@SiO 2 particles for dyes removal are similar or higher than those of other LDH-based adsorbents (Table S18) [33,[46][47][48][49][50][51][52][53][54]. ...

... These findings are consistent with results reported by Li et al. [47], where biochar modified with ZnSO 4 and FeCl 3 exhibited a significant increase in specific surface area and pore volume compared to unmodified biochar. For example, the specific surface area of Mikania micrantha Kunth biochar increased from 4.2 m 2 g −1 to 54.1 m 2 g −1 after modification, with a corresponding increase in pore volume from 0.02 to 0.14 cm 3 g −1 . ...
