Paper Title:
Inhibition of [NH2Et2][(4-MeC6H4O)2PS2] for Carbon Steel in Hydrochloric Acid Solution
  Abstract

The inhibition effect of N,N-diethylammonium O,O'-di(4-Methylpheny)dithiophosphate (NOPP, [NH2Et2][(4-MeC6H4O)2PS2])against the corrosion of carbon steel in HCl solution was studied by weight loss measurements, electrochemical measurements, AFM and SEM techniques. The studies of weight loss measurements indicate that the NOPP acts as a good inhibitor for the corrosion of carbon steel in HCl solution. Polarization curves indicate NOPP is a mixed-type inhibitor. The adsorption of NOPP on carbon steel surface obeys the Langmuir isotherm, and the obtained standard free energy of adsorption suggests that the chemisorption takes place spontaneously.
