【Abstract】 The film growth hypothesis of cinnamaldehyde(CA) on iron in hydrochloric acid is supported by the results of in-situ SERS spectra.It is shown that both the adsorption of CA and formation of a polymer film as a result of the former are two key factors of the inhibition mechanism.Surfactant dodecyl benzyldimethylamomum bromide(DBDAB) play important role in facilitating the adsorption.更多还原
