Impact Of Different Concentrations Of L-Ascorbic Acid On The Particle Size Of Copper Nanoparticles

Abstract

Compared to traditional chemical reducing agents, L-ascorbic acid is better for the environment since it can convert copper ions (Cu²⁺) to copper nanoparticles (Cu⁰) under mild conditions. Its effectiveness stems from the fact that it facilitates the manufacture of small, uniform nanoparticles via its remarkable reduction power. In the colloidal solution, L-ascorbic acid serves as both a capping agent and a stabilizing agent, preventing nanoparticle aggregation. With respect to the size of CuNPs, the quantity of L-ascorbic acid is crucial. As mentioned in the paper, copper nanoparticles (Cunps) were created in an aqueous medium with the help of L-ascorbic acid, which served as both a reducing and capacitating agent. The purpose of the research was to determine the effect of different amounts of L-ascorbic acid on the size of Cunps particles. Two spectrophotometers, one for visible light and one for far infrared, were used to examine the constructed Cunps. Findings show that increasing the quantity of L-ascorbic acid causes a decrease in copper nanoparticle size.
