    Photoelectrochemical Comparative Studies of the Inhibiting Action of BTA and 4CBTA on Copper

    • 摘要: 采用光电化学方法和交流阻抗方法将不同浓度的BTA(苯并三氮唑)和4CBTA(4-羧基苯并三氮唑)在硼砂缓冲溶液(pH9.2)中对铜电极的缓蚀性能作了比较。发现在阳性向电位扫描中,一定农度的BTA作用下,铜电极光响应由p型转化为n型,并可依此判断缓蚀剂的缓蚀性能。n型光响应越大,缓蚀剂的缓蚀性能越好;而在4CBTA作用下,铜电极光响应保持p型,然其阴极向扫描中最大光电汉变化明显,并可据此判断缓蚀剂诉
