Abstract : |
The performance of bark and leaf solution extracts of mango (Mangifera Indica) on the corrosion inhibition of mild steel test specimen immerse in 0.2M dilute sulphuric acid at ambient temperature was investigated. The experimental work was performed by using the weight-loss method and potential measurement technique. Solution extracts were made from the bark and leaves of the tree. The results obtained showed that the bark and the leaves, separately used, will provide very little inhibition. The combination of the two, however, at a concentration of 1.0ml/100ml of 0.2M dilute sulphuric acid, gave very good results that could make it a very useful inhibitor at the ambient temperature. Part 1 of this paper published in the March, 2001, issue, described the experimental procedure employed, and gave a discussion of the results from using the mango bark solution extract alone. The effects of the leaf solution, and of the combined solution, are discussed and analysed in Part 2, published below., |
