Measurement of Hydrogen Produced during Magnesium Corrosion in Hydrochloric Acid and the Effect of the Triton X-100 Surfactant on Hydrogen Production
Abstract
The goal of this article is to measure hydrogen
produced during the corrosion of magnesium in HCl and
the influence of the Triton X-100 surfactant on hydrogen
production. It was found that the hydrogen produced during
corrosion of Mg in HCl increased with increasing HCl concentration,
stirring rate, temperature, and time of immersion.
The addition of the Triton X-100 surfactant inhibits
the amount of hydrogen evolved. The inhibition behavior
was explained on the basis of adsorption of Triton X-100
molecules on the Mg surface creating a barrier for mass
and charge transport, which protects the Mg surface from
aggressive ions. The activation thermodynamic parameter
values were calculated and explicated. Some theoretical
chemical parameters were also calculated. The results
obtained from the theoretical calculations are in agreement
with the practical results.
