Abstract
In this study, a chitosan/copper (Ch/Cu²⁺) polymetallic complex was synthesized from chitosan obtained by the cryogenic method from Apis mellifera bees. The structural and physicochemical properties of the complex were investigated using FTIR, UV-Vis, XRD, TGA, and DLS analyses. FTIR spectra showed shifts in absorption bands at 1400-1339 cm⁻¹ and 1640-1550 cm⁻¹, confirming the coordination of Cu²⁺ ions with amino and hydroxyl groups. UV-Vis spectra revealed absorption peaks in the 410-540 nm range, while XRD analysis indicated new crystalline peaks at 2θ = 24°, 27°, and 37°. Thermal analysis demonstrated high thermal stability of the complex, and DLS confirmed a uniform distribution of nanoparticles in solution. A 0.5% Ch/Cu²⁺ solution was tested against phytopathogens causing rust disease in winter wheat. No negative effects on seed germination or growth were observed. Compared with the “Titul Duo” preparation, the complex exhibited higher biological efficacy. The results indicate that this material is a promising and environmentally safe bioprotective agent for agricultural applications.
