Inhibiting evaluation of β-Cyclodextrin-modified acrylamide polymer on alloy steel in sulfuric solution
Source abstract
Abstract
Abstract The inhibiting performance of β-Cyclodetrin-modified acrylamide polymer (poly(AM-co-A-β-CD-co-NaAA)) on X70 steel in 0.5 M H 2 SO 4 solution has been investigated using potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The polarization curves results reveal that polymer acts as a mixed-type inhibitor. The inhibition efficiency is found to increase by increasing the polymer concentration up to maximum 84.9% for 150 mg L −1 at 303 K. The adsorption is confirmed to obey the Langmuir isotherm. The SEM and EDS results demonstrate that X70 surface is protected by β-Cyclodextrin-modified acrylamide polymer.
