Exploring the properties of uranyl nicotinate: Synthesis, characterization, and thermal analysis

Abstract

This study reports the successful synthesis and characterization of a uranyl nicotinate compound, UO2(C6H4NO2)2·0.25H2O. The compound was synthesized using a metal 1:2 ligand ratio and water as the solvent. The average yield of the compound was 67 %. Thermogravimetric analysis revealed multiple stages of mass loss, including dehydration, nitrogen decomposition and UO2 2+ reduction. Fourier-transform infrared spectroscopy confirmed the coordination of the carboxylate group in the compound. Field emission gun scanning electron microscope analysis showed the particles with a regular oval shape. Energy-dispersive X-ray spectroscopy provided semi-quantitative data on the elemental composition of the compound. The major elements identified were uranium, carbon, oxygen and nitrogen. These results contribute to understanding the compound’s synthesis, thermal behaviour, molecular composition, particle morphology and elemental composition. Further research can build upon these findings to explore potential applications and develop new compounds with tailored properties.
