英文摘要	A green and environmentally friendly inhibitor based on salicylaldehyde-modified chitosan Schiff base was synthesized and its inhibition performance was studied by corrosion product analysis and electrochemical measurements in 1.0 M HCl. The chitosan Schiff base was characterized by Fourier-transformed infrared (FTIR) and the Q235 steel surface morphological was characterized via scanning electron microscope (SEM). The inhibition efficiency increased and the corrosion rate decreased with increasing concentrations of Schiff base. A maximum of 92.72% inhibition efficiency was achieved using 2000 ppm of Schiff base. The polarization measurements showed that the Schiff base acts as both cathodic and anodic inhibitor. The electrochemical impedance studies confirmed that the chitosan Schiff base was adsorbed on the metal surface. Langmuir isotherm provided the best description on the adsorption nature of the inhibitor via both chemisorption and physisorption. SEM analysis indicated the presence of protective film formed by chitosan Schiff base on the metal surface. © 2019, Springer Nature Switzerland AG.
