“…The adsorption isotherm explained the anti-corrosion effect of the synthesized nanocomposite where the adsorption on the metal surface blocks the active sites or forms a protective barrier on mild steel surfaces. Khamis et al had reported that the anti-corrosion effect of algae extracts has strong adsorption on the metal surface (Khamis et al, 2016). From the calculated degree of surface coverage, it was possible to study different adsorption isotherms.…”

Chemical corrosion and bio-corrosion in water pipelines are the most common problem in the industry worldwide which cause damage to expensive equipment and increase the maintenance costs. In the current study, the nanocomposite composed of ZnO and CuO nanoparticles was successfully synthesized using brown algae (Sargassum muticum) extract and then dispersed in polyethylene oxide polymer. The synthesized nanoparticles were exposed to gamma radiation to reduce their particle size. The synthesized nanocomposites were characterized using UV-vis spectroscopy, Dynamic light scattering (DLS), X-ray diffraction (XRD), Transmission electron microscopy (TEM), and FTIR analysis, then, the anti-biofilm and anti-adherence efficacy of nanocomposite were evaluated. The results revealed that gamma radiation reduced the particle size of ZnO and CuO nanoparticles to l5 and 20 nm, respectively. Also, the results showed a significant reduction (P < 0.001) in biofilm formation and adherence of Proteus mirabilis (P. mirabilis), Pseudomonas aeruginosa (P. aeruginosa), and Staphylococcus aureus (S. aureus) to carbon mild steel coupon C1010. In addition, from all the tested strains, P. mirabilis caused the highest bio-corrosion rate 1.5 mpy on mild steel coupon and nanocomposite prevented its adhesion as confirmed by Scanning electron microscope (SEM). Furthermore, the nanocomposite at 150 ppm showed the highest anti-corrosion activity 92.3% in 1 M HCl and exhibited mix-type inhibitor (cathodic and anodic). Finally, the results concluded that the green synthesized nanocomposite had multi-function to be used as anti-biofilm, bio-corrosion inhibitor, and anti-corrosion.

“…Eco-friendly natural products have been explored as metal corrosion inhibitors, a considerable number of plant species and phycophyta extracts proved to have high corrosion inhibition efficiencies [1][2][3][4][5][6][7][8]. Wild flora is considered a good resource for large number of active chemical compounds [9][10][11][12].…”

Bi-functional effect of Eryngium bourgatii extract on inhibiting iron corrosion and bacterial growth in both fresh and marine water media was studied using weight loss measurements for corrosion inhibition and well diffusion method for bacterial growth inhibition. At 150 mg/100 mL inhibition efficiency of corrosion reached 95% and 91% in fresh and marine medium respectively. The results showed clearly that E. bourgatii ethanol-hexane crude extract is strongly active in both media. Three quantitative methods were applied for measuring corrosion rate of iron metal cylinders: relative weight loss, iron released in the medium, and turbidity. Statistical analyses showed that the three methods are comparable and any method of the three could be used to measure corrosion rate. Experimental data obeyed Langmuir isotherm model. Optical and scanning electron microscopy (SEM) images revealed the smoothness and homogeneity of adsorption layer on the iron nail surface. Regarding bacterial growth inhibition at ratio of 150 mg/100 mL medium was found to be effective.
