The persistent discharge of tetracycline (TC) antibiotics into water bodies necessitates the development of efficient and sustainable adsorbents. This study presents a superadsorbent bio-MOF composite derived from durian rind waste, synthesized via an in-situ solvothermal process. The cellulose/zinc terephthalate (Cello/Zn-BDC) composite features a hierarchically structured, fractal surface (Df = 2.65) with uniformly dispersed Zn-BDC crystals, thereby enhancing its accessible interfacial area. The material demonstrates an exceptionally high TC adsorption capacity of 1173.6 mg.g−1 at pH 3, T = 30 °C, t = 720 min, and Co = 300 mg.L−1. This performance is attributed to a synergistic, multi-mechanism process involving coordination to Zn2+ sites, hydrogen bonding to cellulose hydroxyls, π-π stacking with aromatic linkers, and electrostatic interactions. Kinetics follow a pseudo-second-order model, confirming chemical interaction in the primary adsorption layer, while isotherm analysis reveals multilayer adsorption on a heterogeneous surface. Thermodynamic data indicate that the process is spontaneous and exothermic. This work highlights the successful valorization of agricultural waste into a high-performance, sustainable adsorbent for antibiotic removal, aligning with circular-economy principles for advanced water remediation. © 2026 Elsevier B.V.
