Abstract
The weight loss method was used to study the corrosion inhibition of mild steel in 1.5M nitric acid solution with Jathropha tranjenensis extract. The extract of Jathropha tranjeneesis was found to be an efficient corrosion inhibitor of mild steel in nitric acid solution, which worked as a corrodent. The extract was characterized by GC-MS and Infra-Red (IR) spectrophotometer, The infra-red (IR) spectra analysis of jathropha trajenensis indicated the presence of the following functional groups and their frequency ranges which includes; O-H stretching vibrations (3790-3390), C-H stretching (2953-2752), N-H stretch(1643-1514),C=N symmetric stretching (2723-2351) bending, N=O symmetric stretching (1460-1305), C-N stretch (1265-1033),C=O stretching (1651-1566) and C=C bending (1033-721), this further indicates the presence of alcohol, carbonyl compounds, amines and aromatic compounds present in the extract. The weight loss of mild steel in corrodent solutions containing mixes of the leaf extract and 1.5M nitric acid was significantly lower than in the control corrodent of nitric acid alone. This demonstrated that the extract of jathropha trangenensis performed a significant impact in suppressing the corrosion of mild steel by nitric acid solution. The discovery suggests that jathropha tragenensis serves as a corrosion inhibitor for mild steel in nitric acid solution. The presence of oxygen, nitrogen, and aromatic components in the extract’s structure was ascribed to its inhibitory ability.
