摘　　要：采用程序升温脱附法、极化曲线法、失重法及盐雾试验等方法研究了不同类型的缓蚀剂（胺类化合物、环己酮、乙酰乙酸乙酯及杂环类化合物）对模拟文物──低碳钢试样的缓蚀效率及吸附性能．实验证明，苯并三氮唑（ＢＴＡ）在较低浓度时对铁器的缓蚀效率要比保护铁器常用的胺类缓蚀剂（碳酸环己胺与亚硝酸二环己胺）更高，并且ＢＩＡ还具有较低毒性、较易购置等优点．he absorbtion ability and inhibition efficiency of various inhibitors for mild steel have hen investigated by means of thermal programmized desorption, weight-loss test,polarization curve method and salt-fog test. These inhibitors include amine inhibitors,cyclohexanone, ethylacetoacetate and heterocyclic inhibitors. The results show that in relatively low concentration(10-2 mol. L-1), the inhibition efficiency of BTA is better than that of amine inhibitors. Besides, BTA is easier accessable and less poisonous.
