%X types of carbonyl derivatives of benzotriazole (BTA) were synthesised by direct reacting BTA with their respective acid chlorides. Their inhibitive properties for copper in 3% NaCl solution were determined using the Differential Pulse Anodic Stripping Voltammetric Method (DPAS). Results showed that among the 7 types of BTA derivatives synthesised, the inhibitive property of glutaryl/BTA for copper was superior to BTA; while C5/BTA was inferior to BTA; the remaining 5 types were slightly superior to BTA. The conventional weight loss method requires over 6 months to complete. The DPAS method developed can be used to monitor the trace amount of copper during a day and can provide a convenient, rapid and reliable method to measure the corrosion rate of metals.
