| Περίληψη: | Due to their environmental durability and potential for bioaccumulation, bisphenol compounds result in serious threats to biological systems and human well-being, necessitating the development of extremely effective analytical techniques for trace-level monitoring. In this work, a sacrificial-template strategy was employed, in which ZnO served as both the structural scaffold and precursor to direct the controlled growth of ZIF-8, resulting in a hierarchical micro-mesoporous ZnO@ZIF-8 composite. This architecture effectively mitigated the mass-transfer limitations commonly associated with conventional microporous metal-organic framework materials. When employed as a dispersive solid-phase extraction adsorbent, the composite reached adsorption equilibrium rapidly within 3 min, offered ultralow detection limits (0.03-0.1 ng mL-1), and showed high adsorption capacities of 381-408 mg g⁻¹. These characteristics confirm its strong potential for the highly sensitive analysis of bisphenol pollutants in intricate environmental matrices. (Copyright © 2026 Elsevier B.V.
