Plant Extracts for Inhibitory Protection of Steel

详细

New environmentally friendly corrosion inhibitors for mild steel that are based on plant raw materials, basil, cinnamon, sage, clove, spirulina, and pomegranate are proposed for the protection of industrial equipment. Extracts of clove, sage, and basil at 10 cm³/dm³ in tap water provide protection of 91.29–94.65%. In a 0.1 M hydrochloric-acid solution, the maximum anticorrosion action is observed for the extracts of sage and basil at 20 cm³/dm³ (90.11%) and for a pomegranate-peel extract at 30 cm³/dm³ (93.39%).
