“…Due to the presence of acid metal started to dissolute it and inhibitors used to stop the above process. Among different type of inhibitors green and low cost inhibitors get more attention than the chemical type inhibitors, [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41] in acid medium these inhibitors adsorbed on the low carbon steel surface through chemisorptions or physiorption or both process. For the development of low cost and eco friendly inhibitors various materials used as corrosion inhibitors including green plant extracts , food additives, crop plan wastes and oral drugs , among this expired drugs used as corrosion inhibitors by using this we lower the disposal cost of expiry drugs and reduce the pollution caused by the expiry drugs.…”

Frisium anticorrosive activity in corrosive environments was investigated. The performance of the inhibitor as studied by weight loss method along with surface morphological experiments SEM and AFM. The drug showed higher anti corrosive activity 91.66 % in 500 ppm, the above results further showed the scale of inhibition is depends on the concentration of frisium by increasing the concentration the inhibition efficiency of the drug as increased as well as increasing the temperature the inhibition rate was decreased. Impedance results showed charge transfer takes place between the metal surface and acid solution and frisium performed as a mixed type of inhibitor has proven by the polarization measurements. The drug was heavily adsorbed on the low carbon steel surface and is revealed by SEM and AFM studies. By analyzing the DFT values which leads to the accumulation of a thin layer on the metal surface. IR spectral studies have also confirmed the drug's adsorption on the metal surface.

“…The focus of research has shifted to developing green corrosion inhibitors for a variety of corrosive media (Barbouchi et al , 2020; Bharatiya et al , 2019; Dong et al , 2011). Several experiments have been carried out to see whether extracts from natural materials can be used as corrosion inhibitors (Gopiraman et al 2011; Nasser, 2017; Verma et al , 2021a, 2021b). Natural extracts are inexpensive and environmentally friendly (Bendahou et al , 2006; Chaubey et al , 2021; Durvas Seshian et al , 2020; Eddy and Odoemelam, 2009; Fouda and Elattar, 2012; Gupta et al , 2018a).…”

Purpose Plant development and use as green corrosion inhibitors are already recognized as one of the most environmentally friendly and effective protocols. In recent years, efforts have been made to find green corrosion inhibitors as an alternative to synthetic inhibitors for metals in acid medium. This paper aims to report the investigation of use of aqueous extracts of Tamarindus Indica as green inhibitors for corrosion of metals within different circumstances. Design/methodology/approach The use of Tamarindus Indica extracts (leaves, stem, fruit pulp and fruit husk) as corrosion inhibitors for mild steel and aluminum in different mediums (HCl, H2SO4, formic acid and citric acid) at different temperatures was investigated. Findings The inhibitory efficiency of Tamarindus Indica extracts increases with increasing concentration and decreases with increasing temperature. Langmuir is the adsorption isotherm, and the extract (inhibitor) is a mixed-type inhibitor (physisorption and chemisorption). Practical implications Tamarindus extracts (leaves, stem, fruit pulp and fruit husk) are effective inhibitors and can be used to protect metals from corrosion at different circumstances. Originality/value To the best of the authors’ knowledge, this is the first review that discusses the use of Tamarindus Indica extracts as corrosion inhibitors for metals.

“…Although the selection of natural inhibitors successfully inhibits corrosion activities, the inhibitor remains inadequate to protect the bare metal due to low inhibition efficiency of 53.18 %, according to potentiodynamic polarization measurements. The limitation of the research was addressed by the introduction of Morinda citrifolia [16] and fitted the requirement for low carbon steel protection under the same solution. The work reports an improvement in inhibition of nearly 77 %, with the lowest corrosion rate of 1.385 mpy.…”

The work provides the more comprehensive development of Liquid Smoke from Rice Husks Ash (RHA). Notably, the study focuses on the interaction between the primary molecules of inhibitor and mild steel, including thermodynamic calculation and surface treatment upon addition of inhibitor. The electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) characterization were utilized to evaluate the anticorrosion of RHA. The Raman Spectroscopy pre and post-addition of RHA’s inhibitor were used to compare the adsorbed functional group of inhibitors. Moreover, the thermodynamic calculation of the inhibitor’s adsorption determines the types of adsorption of the inhibitor. As a result of the adsorption process, the Scanning Electronic Microscope-Energy Dispersive X-Ray (SEM-EDX) aided by The Atomic Force Microscopy (AFM) and Contact Angle Test was implemented to unveil the surface treatment and the change of elemental composition after the addition of an 80 ppm inhibitor. The PP and EIS results show a significant depression of the current density at ‒2.75 μA·cm2 in 80 ppm solution with the highest inhibition efficiency of 99.82 %. The superior inhibition correlates to the adsorption of Si–OH, C–C, C–O–C, >C=O, complex structure, and –OH at wavenumber 458, 662, 1095, 1780, and 3530 cm-1. The LS shows a significant surface area of protection of 0.9982 and high adsorption constant (Kads) at 11.648. The calculated ΔGads of ‒6.59 kJ/mol unveils the chemisorption in nature. At the same time, a combination of 20 and 80 ppm solution is predicted adsorbed horizontally to reduce the contact between the solution and substrate, as shown in SEM and AFM results. It also increases the contact angle and their corresponding hydrophobicity
