Carbon Steel Corrosion Inhibitor - Europe PMC

Evaluation of Adding Natural Gum to Pectin Extracted from Ecuadorian Citrus Peels as an Eco-Friendly Corrosion Inhibitor for Carbon Steel.

Pectin was derived from Tahiti limes and King mandarin in lieu of natural gums-xanthan gum and latex from the "lechero" plant, which were used to produce an eco-friendly corrosion inhibitor. Pectin extraction conditions were determined from a variety of combinations of pH, temperature, and time in a 23 factorial scheme and assessed according to the resulting pectin yield. According to the increase of inhibitory molecules on the metal surface, the addition of xanthan gum to pectin increased the corrosion inhibitor effect from 29. 20 to 78. 21% at 400 ppm.

Green inhibitor of carbon steel corrosion in 1 M hydrochloric acid: Eruca sativa seed extract (experimental and theoretical studies).

The investigation of Eruca sativa seed extract as a green inhibitor for carbon steel dissolution in 1 M hydrochloric acid solution was investigated. We investigated the surface morphology of the carbon steel using different methods in addition to these methods. The adsorption of Eruca sativa seed extracts on the alloy isotherms for Langmuir and Henry. The relationship between the calculated % IE from experiments and the theoretical analysis was established.
