Abstract:

To lower the rate of mild steel industrial corrosion, the nanoparticle-modified activated carbon (NMAC) is utilized. Co-precipitation technique was used to synthesize activated carbon (AC) and nanoparticle ZnO- or NiO-modified activated carbon (NMAC). The surface morphology and size of the resulting modified nanoparticle and carbon steel were characterized by SEM, EDS, FTIR and TEM analysis. The corrosion rate and inhibition efficiency of mild steel is calculated by weight reduction method in 1 M HCl solution. The corrosion rate of mild steel decreased with modified activated carbon, especially NiO NPs. In NiO NPs and NiO-AC nanocomposites, mild steel inhibition efficiency in 1 M HCl at ambient temperature is 43.69% and 38.59%, respectively.
