Hairy bamboo leaf extract as an eco-friendly corrosion inhibitor for L245N steel in CO2-saturated oilfield produced water
Abstract The inhibition of the corrosion of L245N steel in the CO2-saturated oilfield produced water by the extract of hairy bamboo leaf extract (BLE) has been investigated using electrochemical experiment (EIS), weight loss test, Fourier transform infrared spectroscopy (FTIR), molecular dynamics simulation (MD), and scanning electron microscopy (SEM). The results showed adsorption of BLE on the surface of L245N steel conforms to the Langmuir isothermal adsorption. Electrochemical measurements indicated the maximum inhibition efficiency of 98.76 % at 45 °C and 4 (%v/v). FTIR analysis showed that the BLE contains functional moieties such as O–H, N–H, C=O, C=C, C–N, C–O, and orientin as the effective compound. SEM illustrated that with the addition of BLE, the corrosion of L245N metal is significantly reduced. MD simulation showed that BLE molecules tend to adsorb on the Fe surface, forming an inhibitor film.
期刊介绍:
Corrosion Reviews is an international bimonthly journal devoted to critical reviews and, to a lesser extent, outstanding original articles that are key to advancing the understanding and application of corrosion science and engineering in the service of society. Papers may be of a theoretical, experimental or practical nature, provided that they make a significant contribution to knowledge in the field.
