In this study. the Cu nanoparticles were prepared by reducing CuSO4. These particles were used in making copper nanoparticles modified carbon paste electrode (nano-CPE). The electrochemical characteristics of this electrode (nano-CPE) were investigated. https://www.diegojavierfares.com/quick-offer-Little-Ollie-174-Dwarf-Olive-Monrovia-super-sale/
