摘　　要：通过失重法研究了 2 -巯基嘧啶 (2 -MPM)在盐酸溶液中对锌的缓蚀作用 ,求出了ΔH活化能、指数前因子、速率常数 ,并用吸附理论讨论了缓蚀机理 .Mercaptopyrimidine has been examined as a corrosion inhibitor for Zinc in HCl solution by weight loss method.The state function ΔH ,activation energy,frequency factor and reaction rate constant of corrosion reaction in the presence and in the absence of the inhibitor have been evaluated.The results of the experiments were discussed in the light of Langmuir adsorption theory.
