Comparative Study of Corrosion Inhibition Efficiency of Phyllanthus niruri for Tin in Different Solutions of HCl and H2SO4.
Journal Title: IOSR Journal of Pharmacy (IOSRPHR) - Year 2017, Vol 7, Issue 7
Abstract
Abstract: The corrosion inhibition of tin in different solutions (1N, 2N, 3N) of HCl and H2SO4 by the leaves extract of Phyllanthus niruri has studied by using weight loss and thermometric methods at 303K temperature inhibition was found to increase with increasing concentration of the extract. Results indicate that Phyllnthus niruri leave extract was an efficient natural corrosion inhibitor in the acidic media. In case of 3N HCl maximum inhibition efficiency (96.96%) was noted at 0.7% in inhibition concentration and in 3N H2SO4, it was found 91.30% efficiency at the same concentration of inhibitor. At lower concentration of inhibitor, better inhibition was observed in H2SO4 medium as compared to HCl. The decreased corrosion rate of metal was due to absorption of plant extract on metal surface. Absorption of Phyllanthus niruri depends on its chemical compositions which showed the presence of various compounds like alkaloids, flavonoids, steroids, tannins etc. which has O, N and S atoms with lone pair electrons to form co-ordinate bonding with metal.
