This paper reported the synthesis of copper nanoparticles (Cu-NPs) via the chemical method in the presence of CuSO4.5H20 as precursor, polysaccharide as a stabilizer and ascorbic acid was acted as a reducing agent. In this study, the irradiation time was varied to evaluate the effect of time exposure with the Cu-NPs production. The analysis of samples without and with polysaccharide was characterized using ultraviolet-visible (UV-Vis) spectroscopy, X-ray diffraction (XRD) and Fourier-transform infrared coupled with attenuated total reflection instrument (ATR-FTIR). Based on the observation, reddish-brown colour solution demonstrated the formation of Cu-NPs and UV-Vis proved the plasmon resonance (SPR) spectra at the peak of 580 nm. The sharp peak of XRD at angle 2O gives the value of 43.69°, 50.81°, and 74.42° was attributed to Cu-NPs and the presence of polysaccharides maintained the crystallinity of Cu-NPs. FTIR results shows that the interaction peaks were occurred based on shifting of the peak to higher wavenumber. In conclusion, Cu-NPs were successfully produced by using the microwave method and be a function of time.
