摘　　要：介绍了304L不锈钢-浓硫酸阳极保护体系的研究。研究确定了阳极、阴极、参比电极材料以及电流密度及保护电位等重要参数。根据该研究结果设计、制造的阳极保护浓硫酸循环槽、储槽成功应用于硫酸装置。现场实践证明,阳极保护304L不锈钢浓硫酸槽耐浓硫酸腐蚀性能优良。The anodic protection system of 304L stainless steel-concentrated sulphuric acid was researched. Anode and cathode materials and some important parameters such as current density and protective potential were determined. The anodically protected concentrated sulphuric acid circulation tanks and storage tanks designed and manufacted according to the results were used in sulphuric acid plants successfully with good corrosionresitant effects.
