Schiff’s base derived from the pharmaceutical drug Dapsone (DS) as a new and effective corrosion inhibitor for mild steel in hydrochloric acid

Schiff’s base derived from the pharmaceutical drug Dapsone (DS) as a new and effective... The inhibition ability of Dapsone’s Schiff’s base with salicylaldehyde (1:2) for mild steel corrosion in 1 M HCl solution at 308 K was studied by means of potentiodynamic polarization, electrochemical impedance spectroscopy techniques, and gravimetric analysis. Results showed that Dapsone salicylaldehyde performed well as a good inhibitor for mild steel in 1 M HCl solution with maximum inhibition efficiency of 95 % at 500 ppm. The adsorption isotherm of the inhibitor followed the Langmuir adsorption. The value of free energy of adsorption showed that it is a spontaneous process and followed typical physical adsorption. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
