摘要
已有测试腐蚀速率的分光光度法在现场使用中受酸化液中添加剂的影响。本工作成功地建立了邻菲罗啉分光光度法测试铁离子浓度的方法。实验验证了此法的可行性。和传统的失重法相比,铁离子浓度分析法不但可用于实验室,而且可用于现场腐蚀监测和连续腐蚀速率测试。室内试验表明该方法具有简易可行和准确度高的优点。
The Fe ion concentration was determined by phenanthroline spectroscopic analysis, and some influence of additives had been precluded through well stimulation. Comparing with the typical method of weight loss, the new method could be used not only in laboratory but also in field monitoring and testing the corrosion rate continuously. It is convenient and highly sensitive, could be applied to corrosion research.
