Electrochemical study and adsorption parameter investigation of copper in a chicken bone ash inhibited NaCl environment

Abstract

Abstract By examining the corrosive behaviour and adsorption characteristics of copper in a corrosive medium containing 0.5 M NaCl, the potential of chicken bone as a corrosion inhibitor was examined in this study. With inhibitor concentrations ranging from 0.2 to 0.8 g, the experiments were carried out at temperatures between 30 and 60°C. The effectiveness of chicken bone ash as a corrosion inhibitor was evaluated using a variety of electrochemical analysis techniques, such as polarisation analysis and open circuit potential measurement. The electrochemical analysis' findings demonstrated that chicken bone ash functions as a cathodic inhibitor, significantly slowing copper corrosion. The inhibitor outperformed all other concentrations tested and demonstrated its maximum inhibition efficiency at a temperature of 50°C. These findings were further supported by the adsorption parameter analysis, which showed that the copper surface responded quickly to the inhibitor's adsorption, primarily through a physical adsorption process. A promising alternative for protecting copper in corrosive environments is the use of chicken bone as a corrosion inhibitor. The findings imply that chicken bone ash has inherent inhibitory properties that effectively slow down corrosion.
