“…The chemical constituents of green tea made it a better corrosion inhibitor. When an inhibitor was present, the value of I corr dropped dramatically compared to when none was present [ 40 , [48] , [49] , [50] ]. Table 3 shows the EIS parameters.…”

“…A recent study shows Corrosion may be reduced by 71.43% when green tea extract is used in the weight loss strategy, and by 85.711% when tulsi extract is used instead. In 10% H 2 SO 4 , tulsi extracts had a more noticeable anti-growth impact than green tea extracts [ 40 ]. The inhibitory performance was determined using weight loss and electrochemical corrosion tests.…”

“…It is suspected that the produced water is contaminated with H 2 S. The weak acid darkens the coupon and inhibits the adsorption of the inhibitor on the surface of API 5L Grade A. A shorter immersion time is also predicted to give better protection since the remaining compound is fully adsorbed at the active sites [38].…”

This work used soursop as a green corrosion inhibitor to protect API 5L Grade A from detrimental corrodent under produced water. Despite the effectiveness of inorganic inhibitors, recent evidence on their toxicity test suggests that implementing organic inhibitors is substantial to replace synthetic corrosion inhibitors. However, soursop utilization as a green corrosion inhibitor is poorly understood due to the lack of a comprehensive extraction mode and inhibitive mechanism. Several tests were conducted, including weight loss, potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS), to unveil the nature of corrosion inhibition. Fourier Transform Infra-Red Spectroscopy revealed the dominant functional groups to bind with the substrate. The potentiodynamic polarization results show that the inhibitor is a mixed-type inhibitor that influences the anodic and cathodic reactions. The weight loss test showcases the highest inhibition efficiency of 52.62 % upon adding 2 ml inhibitors upon eight observation days. The polarization and EIS results provide that the inhibitor reduces the corrosion rate with higher inhibition of 88.52 %. The mentioned result is associated with the attachment of non-polar and polar Annona muricata Linn functional groups. The primary functional group involves C=O, C‒C and –O.H., which actively bonded to the metal's surface. The aromatic group at a wavenumber of 1,050 and 1,090 cm-1 shows ether's presence and behaves as an adsorption center. In this work, combining three solvents, hexane, acetone, and ethanol, elicits the complete extraction of the predominant compound from soursop
