Formation kinetics and optoelectronic parameters of CdSe (NPs) addition to Nonionic Surfactant as a factor influencing the corrosion inhibition potential of Carbon Steel in Hydrochloric Acid

Abstract

In the present study, CdSe Nanoparticles (NPs) as a corrosion inhibitor factor, has been added in small concentration (0, 1, 2, 3, 4 wt%) to nonionic surfactant to formulate CdSe/Surfactant nanocomposite (NCs) for industrial applications. The chemistry between CdSe (NPs) and surfactant, is a new class of corrosion inhibitors that are environmentally acceptable under various condition. The inhibition effect towards corrosion was investigated by using structural integrity and optical properties. The structural characterization was carried out by Fourier-Transform Infrared spectroscopy (FTIR), Nuclear Magnetic Resonance (NMR), Surface Tension Measurements (CMC), High Resolution Transmission Electron Microscope (HRTEM), UV–Vis Spectrophotometer and Atomic Force Microscope (AFM). The corresponding dielectric functions (DF) are discussed in the light of the optoelectrical parameters and dispersion parameters. The strong sorption ability of the CdSe (NPs)/Surfactant, resulting in the creation of a monolayer, which isolate the Carbon steel (CS) surface from the environment and hence reduces the corrosion attack on the surface and increase the absorption process as well. The values of the inhibition efficiencies (IE%), was explained in terms of the weight Loss, relevant electrochemical parameters, and charge transfer resistances. The values of (IE%) in this study, showed that it inhibits the (CS) corrosion when immersed in HCL solution to some appreciable extent, and is strongly dependent on the increase of the CdSe (NPS)percent. This work investigates and illustrate a way for the future development of higher performance of corrosion inhibitors.
