| Abstract: | In order to study the composite inhibitor for the zinc in nitric acid,the several monocomponent inhibitor was studied to obtain the optimum ratio by orthogonal design method.Some data（the film′s resistance,the film′s capacitance and the film′s surface coverage）were investigated by electrochemical impedance spectroscope method.Quantum chemical paramenters explained relation between data and effect of corrosion inhibition and reaction mechanism via DFT-B3LYP/3-21g calculation of Gaussian 2003. |
