| dc.description | The corrosion inhibition of Zinc-Aluminum alloy in 1.8 M of hydrochloric acid solution by 2-(1-(2-oxo-2H-chromen-3-yl) ethylidene) hydrazine carboxamide was carried out using weight loss method. Zinc-Aluminum coupons were immersed in test solution of blank and solutions of 0.001 M, 0.002 M, 0.003 M and 0.004 M of the inhibitor at room temperature and 50oC consistently for seven days duration. The percentage inhibition efficiency (% I.E) and surface coverage (θ) of the Zinc-Aluminum was calculated and result indicated corresponding increase with concentration of inhibitor. The adsorption isotherm of the process was estimated using four adsorption isotherm theories namely: Langmuir, Freundlich, Temkin and Frumkin. The adsorption studies revealed that Langmuir isotherm (R2 = 0.9997) is the best model for the adsorption of 2-(1-(2-oxo-2H-chromen-3-yl) ethylidene) at room temperature and at 50oC on Zinc-Aluminum surface. | |
