摘要：采用交流阻抗法研究了在不同pH条件下的3%NaCl溶液中3种缓蚀剂4CBTA、5CBTA、CBT-1在浓度为 40mg/kg时对铜电极的缓蚀行为并与BTA进行了比较.实验结果表明在pH=6及pH=9时这3种缓蚀剂均无级蚀作用,而在PH=3时它们的缓蚀作用比较明显,缓蚀效果均比BTA好,尤以4CBTA缓蚀效果最佳.
The corrosion inhibition for copper electrode in 3% NaCl solutions (pH = 3,6,9) with various inhibitors 4CBTA.5CBTA、CBT-1 AND BTA was studied by using AC impedance spectroscopy. The results show that 4CBTA、5CBTA and CBT-1 have better inhibition for copper 3% NaCl solution at pH = 3, than BTA, especially 4CBTA has best inhibitiion effect, but at pH = 6 and pH = 9 except for BTA they don't show any inhibition for copper.
