SYNERGISTIC INHIBITION EFFECT BETWEEN 3-PHENYL-4-AMINOBENZYLIDENE-5-MERCAPTO-1, 2, 4-TRIAZOLE COMPOUND AND POTASSIUM IODIDE
3-苯基-4-苯亚甲基氨基-5-巯基-1,2,4-三唑与碘化钾的缓蚀协同效应

A new kind of mercapto-triazole compound,namely 3phenyl-4-aminobenzylidene-5-mercapto-1,2,4-triazole(PABMT) was synthesized.The synergistic inhibition effect of the PABMT-KI(potassium iodide) system was discussed on the basis of electrochemical experiments.The mechanism was proposed for the synergistic effect of the inhibiting system.Thermodynamic parameters of adsorption were determined for the PABMT-KI system according to the Bockris-Swinkels isotherm model.
