摘要：采用交流阻抗法研究了在ＮａＣｌ溶液中缓蚀剂ＢＴＡ、ＴＴＡ、５ＭＢＴＡＣＢＴＭＥ对铜电极的缓蚀行为并进行了比较。４种缓蚀剂的缓蚀性均随浓度的增加而增加，当浓度达到７０ｍｇ／Ｌ时缓蚀性最佳。缓蚀剂浓度低于２０ｍｇ／Ｌ时ＢＴＡ、ＴＴＡ、５ＭＢＴＡ有效好的缓蚀性，超过４０ｍｇ／Ｌ时ＣＢＴＭＥ的缓蚀性明显优于其他３种。复合配方试验结果表明，当缓蚀剂总浓度为４０ｍｇ／Ｌ，ＢＴＡ与５ＭＢＴＡ复配的最佳比例为２０ｍｇ／ＬＢＴＡ＋２０ｍｇ／Ｌ５ＭＢＴＡ时，显示出协同效应。
The corrosion inhibition of copper electrode in NaCl solutions (pH6) with various inhibitors BTA、TTA、5MBTA and CBTME was studied by using AC impedance spectroscopies.The corrosion inhibition of these four inihbitors increases with its concentration up to 70mg/L.At the low concentration (below 20mg/L),BTA、TTA and 5MBTA have better inhibition than CBTME and CBTME is the best among them at the concentration over 40mg/L.A combination of BTA and 5MBTA gives a synergistic effect and the optimum ratio with the total amount of 40mg/L is 20mg/L BTA+20mg/L 5MBTA.
