摘要

The potential adsorbent for inhibitors of corrosion in HCl 1.0 M was investigated using experimental and modeling data on a novel cationic polymeric resin composite called Amberlite™ IRC-200. The resin has a significantly better ability to adsorb the Ni(II) ions. Molecular dynamics (MD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and DFT theory were among the methods used to examine the polymeric adsorbent resin. In this work, the adsorbent cationic polymeric resin is used to suppress corrosion in HCl 1.0 M. Experimental results demonstrated that ACQ and DAQ significantly increased MS corrosion resistance; results from Tafel polarization demonstrated that resin polymeric compounds exhibited disordered-type inhibitory properties with varying corrosion rates. Results from the highest best impedance experiments showed that at 100 ppm, ACQ inhibited performance to a 94.9% degree. Adsorption of the cationic adsorbent polymeric resin followed the most recent findings in the Langmuir model, and the most recent estimations of thermodynamic parameters indicated physisorption. Scanning transmission electron microscopy was used to investigate the MS morphological investigation.
