Abstract

Inhibition efficiency of carbon steel alloy type C1025 in 0.1 M HCl at 298 K by Graphene oxide (GO) and phosphorous acid Functionalized Graphene oxide (GOE) were synthesized and characterized by XRD, FT-IR, FESEM, Raman shift and EDX techniques afterward studied by two techniques Tafel plots and Impedance spectroscopy (EIS). The results reveals that inhibition take place during adsorption of GO and GOE on metal surface. Tafel plots reveals that optimal concentration of GO is 100 ppm with inhibition efficiency about 77.4 %, while GOE has 86.8 % at 70 ppm. EIS technique was used to discuss mechanism of inhibition.
