Abstract
Weight loss measurements and potentiostatic polarization studies show that tetrazospiro (5,5) undecane-3-thione (TUT) acts as an effective i nhibitor for the corrosion of mild steel in 1 N HCl and 1 N H2SO4. Thi s is also shown by hydrogen permeation studies by decreasing hydrogen permeation current through mild steel surface. Electrocapillary studie s show that it is adsorbed on both the sides of the electrocapillary c urves. It's adsorption on mild steel from 1 N HCl and 1 N H2SO4 is fou nd to obey Temkin's adsorption isotherm.
