SERS Studies of Corrosion Inhibition of BTA and Its Derivative on Copper Electrodes in NaCl Solution
Abstract:
Corrosion inhibition of benzotriazole(BTA) and its derivative CBTME on Cu in 3%NaCl solution was studied by SERS technique. The inhibition mechanism for BTA and CBTME on copper corrosion in the solution was found to be similar each other, by which a protective film is formed through the triazole ring. The substituent group (-COOCH3) of CBTME plays the role in the inhibition effect due to steric hindrance. A combination of BTA and CBTME showed a synergistic effect and the inhibition mechanism remained the same as individual species.
