“…The thoroughly rinsed corroded metal coupons are re-weighed after specified period of exposure time to check the weight loss. The corrosion rate [72] , surface coverage degree θ [74] and percent corrosion inhibition efficiency η% [75] can then be evaluated using Eqs. (4) , (5) , and (6) respectively.…”

In the past, lives and wealth have been lost due to corrosion in almost all engineering fields. Not only this, the cost of reviving damaged equipments in the industry due to corrosion contributed a lot to the gross domestic product of a nation. Thus, all hands must be on desk to combat this harzadous act via time to time research on its final resolution. However, current research works have revealed effective and reliable corrosion inhibitors from pharmaceutical drugs, plant extracts and ionic liquids as organic green corrosion inhibitors (OGCIs) with accommodative attributes such as being environmentally friendly, readily available, biodegradable, non-harmful, relatively cheap and many others to mention a few. This paper opens readers mind into the detailed classifications, mechanisms and active functional groups of these eco-friendly OGCIs. Not only the corrosion efficiency calculation ways but also influencing factors on efficiency were presented. Plant extracts, pharmaceutical drugs, ionic liquids and synthetic inhibitors, as among major sources of OGCIs, used in preventing material corrosion in corrosive media were separately and comprehensively examined. The significance of values obtained from simulating presented mathematical models governing OGCIs kinetics, adsorption isotherm and adsorption thermodynamics was also included. In conclusion, beneficial recommendations for both current and prospective researchers in the field of Corrosion Engineering were presented.

“…where ∆m is the sample mass loss (g), S the surface area of the specimen (m 2 ), and t the immersion duration (h). The gravimetric analysis is used in this study to quantify the corrosion extent as described elsewhere [34][35][36]. The simplicity and reliability of the measurement offered by the weight in this method are such that the technique forms the baseline method of measurement in many corrosion-monitoring programmers.…”

Crude glycerol, a byproduct of biodiesel production, was evaluated as a potential green inhibitor for steel corrosion in an acidic environment. The study was conducted using steel specimens placed in hydrochloric acid solutions (0.5 M) at a constant room temperature (25 • C) and crude glycerol concentrations in the range 0.1%-1.0% w/w. The criteria used to evaluate the extent of corrosion were the weight loss and corrosion rate. Additionally, fresh and spent samples were characterized using scanning electron microscopy and potentiodynamic polarization measurements. It was found that, generally, the corrosion inhibition increased with the inhibitor concentration. Results also showed that the maximum inhibition efficiency was achieved at 70 h residence time after which the inhibition efficiency at a given concentration either remained unchanged or dropped slight. Additionally, the overall maximum inhibition efficiency (98%) was observed at 70 h residence time and a 1% inhibitor concentration.

“…Os bioinibidores ou inibidores verdes, são uma alternativa para a substituição de inibidores convencionais e a glicerina obtida como resíduo na produção de biodiesel, que tem uma grande demanda atualmente, considerada resíduo, que pode trazer inúmeros benefícios econômicos e ambientais por se tratar de uma matéria-prima amigável ao meio ambiente [6].…”

O uso de inibidores de corrosão verdes vem se destacando ao longo dos anos, e a glicerina como matéria-prima de origem renovável, mostra-se uma boa alternativa a ser usada para desenvolver novos inibidores, substituindo os inibidores de corrosão agressivos ao meio ambiente, por ser de origem renovável e se mostrar amigável ao meio ambiente. O objetivo deste trabalho é avaliar na literatura estudos que tratam sobre inibidores de corrosão verdes e o uso da glicerina como inibidor de corrosão. Nesse contexto foi realizada uma revisão sistemática, com uma busca nas bases de dados, Science Direct, Periódicos Capes e Google Acadêmico, delimitada aos últimos seis anos (2017-2024). Palavras chaves, inibidores de corrosão verdes, inibidores de corrosão e glicerina, glicerina e aplicações industriais. Por meio dessa metodologia foram selecionados 108.491 artigos, e deste total foram extraídos 22 artigos usando critérios aplicados nessa revisão sistemática, as plataformas Science Direct, Periódicos Capes, Google Académico foram os indexadores da busca, após a discussão dos trabalhos selecionados os inibidores verdes e a glicerina de origem renovável ainda podem contribuir muito no setor industrial na área de inibidor de corrosão.
