| Abstract: | The corrosion of copper in 2M nitric acid (HNO3) at 30°C, 40°C, and 50°C have been done. Six time intervals, from one to six hours, were chosen for the present study. Rate of corrosion for all the temperature understudy shows significant corrosion of copper in 2M nitric acid ranging from 4.301 ×10-5 gram cm-2 min-1 to 76.720 ×10-5 gram cm-2 min-1.The results show a strong effect of HNO3 at 2M concentration on copper corrosion. It has been observed that higher temperatures and longer exposure times leading to a considerable rise in corrosion rates. The effect of the addition of organic compounds containing an amino group and thio group such as urea and thiourea on the corrosion of copper in nitric acid was studied by weight loss methods. Results obtained from this study reveal that both urea and thiourea shows a remarkable corrosion inhibition effect with inhibition efficiency of 89.99 % to 99.12 %. However urea was found strong inhibitor than thiourea. Thus thiogroup reduce the inhibition efficiency. |
