Gomphrena serrata Leaf Extract as Corrosion Inhibitor and Reductant for the Synthesis of Copper Nanoparticles

摘要

Adapting eco-friendly methodologies is the need of the hour in the every field of research. In the present work an investigation on Gomphrena serrata leaves was evaluated as a corrosion inhibitor for the mild steel in HC1 medium and as a reductant. The G. serrata as an efficient inhibitor it obeys Langmuir adsorption isotherm and served as anodic type inhibitor. The impedance study confirms the formation of thin film on the metal surface through its Cdi and Rc, values. The copper nanoparticles and their derivatives have been used as a medicine to prevent infection, leg ulcers etc. Gomphrena serrata leaves have good medicinal values, to enhance its medicinal properties it was mediated for the synthesis of copper nanoparticles. The CuNPs formation was confirmed by SPR bands at 345 nm by microwave method and at 341 nm by thermostat method. The functional groups present in the G. serrata also present in the FTTR spectra of CuNPs and it confirms the G. serrata was used as a reducing as well as a capping agent.
