In a groundbreaking study published in ‘Discover Materials’, researchers have revealed that extracts from the Euphorbia neriifolia plant could serve as highly effective green corrosion inhibitors for aluminum, particularly in harsh acidic environments. This innovative approach not only promises to enhance the longevity of aluminum structures but also aligns with an increasing demand for environmentally friendly materials in the construction sector.
Lead author Omprakash Meena from the Regional Institute of Education, NCERT, emphasizes the significance of this research, stating, “Our findings demonstrate that using natural extracts can significantly lower corrosion rates, providing a sustainable alternative to traditional synthetic inhibitors that often carry harmful environmental consequences.” The study highlights the efficacy of Euphorbia neriifolia extracts, achieving inhibition efficiencies of up to 94.92% in 1 M hydrochloric acid and 92.62% in 1 M nitric acid, showcasing a remarkable potential for commercial applications.
The research utilized various methodologies, including weight loss measurements and advanced imaging techniques like Field Emission Scanning Electron Microscopy (FESEM), to assess the protective qualities of the plant extracts. The results indicated a dramatic reduction in corrosion rates—from 157.89 mm/yr to a mere 0.0099 mm/yr—when the optimal concentration of the stem extract was applied. FESEM images further illustrated the protective effects, revealing smooth, intact surfaces of aluminum treated with the extracts, in stark contrast to the rough and pitted surfaces of untreated samples.
This study not only opens new avenues for corrosion management in construction but also addresses the pressing need for sustainable practices. As the construction industry increasingly seeks eco-friendly solutions, the potential commercial impact of such research could be profound. By integrating natural corrosion inhibitors, companies could reduce maintenance costs and extend the lifespan of aluminum components used in various applications, from structural frames to facades.
Moreover, this research aligns with global sustainability goals, offering a biodegradable alternative to conventional inhibitors. Meena notes, “We are at a pivotal moment where the construction industry can embrace greener technologies that not only protect materials but also contribute to environmental conservation.”
As the industry evolves, the implications of this research could lead to a significant shift in how materials are treated and protected, fostering a culture of sustainability while enhancing the durability of construction materials. The findings from this study could pave the way for further innovations in green synthesis and corrosion management, ultimately shaping a more sustainable future for the construction sector.
