Abstract

Ribavirin (RBV) in food and environmental samples presents significant risks to human health, necessitating the development of methods capable of its simultaneous detection and adsorption. This study describes the preparation of a multi-functional molecularly imprinted material (Nylon@Eu-MOF@MIPs), achieved through in-situ growth of Eu-MOF with fluorescence properties on a nylon membrane, designed for the concurrent adsorption and detection of RBV. The material demonstrates high adsorption capacity for RBV (41.36 mg g⁻¹), a pronounced imprinting effect (imprinting factor of 3.06), and substantial sensitivity (detection limit of 0.01 μM). Furthermore, following ten adsorption–desorption cycles, Nylon@Eu-MOF@MIPs retain effective adsorption capacity, with a minimal loss of 5.8 %. Additionally, a filtration-enhanced adsorption and detection mode is proposed, achieving a 1.63-fold increase in adsorption capacity compared to the traditional soaking method. The integrated platform developed in this study facilitates efficient adsorption and visual detection of RBV. This research not only advances membrane separation materials but also establishes foundational conditions for creating integrated systems for simultaneous adsorption and visual detection.

期刊介绍： Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
