摘要

The study of turmeric’s physical and chemical properties (Curcuma Longa) added with copper particles has drawn significant interest for its environmentally benign and long-lasting properties as a reducing and stabilising agent. Utilizing Ultraviolet-visible Spectroscopy (UV-Vis), Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM), the synthesised copper was characterised. The active ingredients found in Curcuma Longa reduced copper ions in an aqueous solution to create copper particles. In UltraViolet Visible Spectroscopy (UV-Vis), increasing concentration led to absorbance fluctuation, attributed to varying solubility of the particle mixture within the wavelength range between 420 nm to 550 nm. The Fourier Transform Infrared Spectroscopy (FTIR) study revealed the molecular composition of copper particles’ transmittance, functional group, and chemical bonds. A broad peak around 3200–3600 cm−1 indicated stretching vibrations of hydroxyl (O-H) groups covering alcohols and phenols. Peaks around 1700–1800 cm−1 indicated stretching vibrations of the carbonyl (C = O) group covering ketones, aldehydes, and carboxylic acids; meanwhile, peaks around 3300–3500 cm−1 indicated stretching vibrations of the amino (N-H) group cover amines and amides bonds. The surface morphology of the synthesised copper particles was examined using Scanning Electron Microscopy (SEM), which provided visual proof of production, revealing that the particle size of Curcuma Longa rhizome extract increases with concentration due to particle mixture insolubility illustrates a smoother copper particle morphology at 3M compared to a rougher texture at 5M. Copper impacts biological systems when the characterisation shows copper particles’ good physical and chemical properties. In conclusion, it enhanced several applications such as catalytic, drug delivery systems and antibacterial effects. Their environmentally benign synthesis process enables a wide range of applications, significantly advancing the safe application of copper in several industries.
