This study presents the synthesis and comprehensive physicochemical analysis of novel oligo(poly)mer sorbents derived from urotropine and cyanuric acid. The sorbents were obtained via controlled polycondensation reactions involving urea-formaldehyde systems modified with cyanuric acid, leading to structurally robust and functionally active oligomers. Advanced characterization techniques—including SEM, XRD, IR spectroscopy, and thermal analysis—confirmed the formation of new materials with unique morphology, crystallinity, and thermal stability. The synthesized CA+UFO(III) sorbents demonstrated high sorption efficiency for various 3d-metal ions (Cu²⁺, Ag⁺, Fe²⁺, etc.), with optimal performance in the pH range of 4–6. Results indicated that cyanuric acid not only enhances the reactivity of methylol groups but also stabilizes the oligomer structure, reducing formaldehyde release during storage. These findings highlight the potential application of CA-modified sorbents in environmental remediation and industrial wastewater treatment, offering an effective, tunable, and eco-friendly approach to selective metal ion adsorption.
