Unveiling the multifaceted incorporation of Musa acuminata peduncle juice as a bio-corrosion inhibitor of mild steel in seawater-simulated solution

Abstract

This work assessed the ability of Musa acuminata peduncle juice extract to sustainably inhibit mild steel under salinized conditions. The effort sought to ascertain the new active material's inhibitory efficacy for inhibiting metal corrosion in seawater. M. acuminata peduncle juice was extracted from the M. acuminata peduncle. The functional group of the M. acuminata pedal juice was determined using Fourier transform infrared spectroscopy. The corrosion behavior was assessed using electrochemical impedance spectroscopy and potentiodynamic polarization by varying the M. acuminata peduncle juice at 0.1, 0.2, and 0.3 g L⁻¹ for 300 K, 310 K, and 320 K, respectively. Scanning electron microscopy provided an image of the surface morphology of mild steel. Reduced corrosion current (i_corr) was observed when M. acuminata pedal juice was present according to potentiodynamic polarization and studies. Moreover, adding M. acuminata peduncle juice increases resistance capacity transfer (R_ct). The potentiodynamic polarization approach was used to obtain the optimum inhibitory efficiency (%IE) at 0.3 g L⁻¹ doses with 88.0% efficiency at 300 K. The addition of M. acuminata peduncle juice results in a smoother, mild steel morphology than the surface without inhibitor additions. The molecules of active chemicals adhering to the steel surface were linked to increased corrosion inhibition. The study's findings demonstrated that M. acuminata peduncle juice is a promising biomaterial for mild steel corrosion inhibitors in a salty environment.
