Testing the Effectiveness of Mango (Mangifera indica) and Apple (Malus pumila) Peels as an Active Ingredient in a Corrosion Inhibitor Spray for Galvanized Iron Pipes
No full textCorrosion in galvanized iron pipes (GIPs) poses significant challenges to water distribution systems, leading to structural degradation and public health risks. This study developed and assessed the efficacy of Mangifera indica (mango) and Malus pumila (apple) peel extracts as active ingredients in a corrosion inhibitor spray for galvanized iron pipes, using maceration to prepare 70% concentration extracts and testing them on GIPs immersed in 3 M hydrochloric acid for eight days. Results showed the combined extract exhibited the highest inhibition efficiency (27.71%), lowest thickness loss (1.449 × 10⁻³ cm), and minimal discoloration, outperforming individual extracts (apple: 23.76%; mango: 10.87%) and the control group, though efficiencies were lower than prior studies due to experimental variations. The findings demonstrate the potential of these eco-friendly spray alternatives, particularly when combined, while highlighting the need for further optimization and long-term testing to enhance practical applications
