SEOUL, South Korea, Oct. 15, 2025/ PRNewswire/– Beta-blockers are commonly recommended pharmaceuticals utilized to handle cardiovascular conditions such as high blood pressure, arrhythmias, and post-heart attack healing. Amongst them, atenolol (ATL) and metoprolol (MTL) are especially typical. Their high chemical stability advantages healing effectiveness however likewise implies they deteriorate gradually, continuing the environment. Standard wastewater treatment plants are mostly inefficient at eliminating these substances, permitting them to get in rivers and lakes, where even low concentrations can apply persistent hazardous impacts on algae, fish, and other water organisms.
To eliminate such consistent pharmaceuticals, scientists have actually checked out the advancement of innovative adsorbent products, such as covalent natural polymers (Police officers). These permeable products can be crafted with varied practical groups, permitting great tuning of adsorption homes. Just recently, Police officers including fluorine atoms have actually gotten substantial attention for their abnormally high adsorption efficiency and subsequently, capacity for eliminating toxic wastes. Yet, couple of research studies have actually explored their application in elimination of pharmaceuticals.
Filling this space, a research study group led by Teacher Yuhoon Hwang from the Department of Environmental Engineering at Seoul National University of Science and Innovation (SeoulTech), examined FCOPs as adsorbents for beta-blockers. “ Our research study reveals that FCOPs are extremely appealing for eliminating consistent beta-blockers from water,” states Prof. Hwang. “ We likewise clarified the adsorption systems that discuss why FCOPs attain abnormally high adsorption capabilities.” The research study was offered online on July 28, 2025, and released in Volume 285, Part 3, of the journal Environmental Research Study in November 15, 2025
The group prepared a FCOP utilizing a basic, catalyst-free one-pot approach and evaluated their capability to eliminate ATL and MTL from water. Extremely, FCOPs showed exceptional adsorption efficiency, eliminating 67.3% of MTL and 70.4% within the very first minute. Remarkably, when the scientists outlined its adsorption efficiency versus beta-blocker concentration, the curve revealed a sigmoidal or S-shaped profile.
At lower concentrations, adsorption increased slowly, constant with the monolayer adsorption impact, where particles get adsorbed onto the adsorbent surface area in a single layer. Nevertheless, beyond a concentration of 60 mg/L, the uptake increased dramatically for both beta-blockers, showing a multilayer adsorption impact. In multilayer adsorption, particles stack in numerous layers, and their interactions can improve adsorption efficiency. This adsorption behaviour sets FCOPs apart from standard adsorbents. Notably, the FCOP preserved this strong adsorption efficiency even in genuine water samples consisting of numerous ions and natural acids.
The group likewise recognized the crucial systems driving this abnormally high efficiency. They discovered that the abundant structure of FCOP, including plentiful fluorine atoms, results in numerous synergistic interactions. Initially, the existence of fluorine results in strong intermolecular interactions in between FCOP and beta-blockers. Second, electrostatic interactions play an essential function in adsorption of the favorably charged beta-blockers onto the adversely charged FCOP particles. Lastly, the hydrophobic nature of FCOP reduces contact with the water, promoting the aggregation of adsorbed particles, helping with multilayer adsorption.
“ These synergistic interactions adequately discuss the exceptional adsorption capability of FCOP. Our findings might function as an important structure for creating next generation adsorbents,” remarks Prof. Hwang. “ In future, these fluorine-rich adsorbents will be important in lowering pharmaceuticals in water environments, not just securing water life, however likewise making sure more secure drinking water.”
By incorporating FCOPs into innovative treatment systems, water energies might better reduce pharmaceutical contamination. This development represents a considerable action towards sustainable filtration techniques that protect environments and human health.
