Study on the synergistic inhibitive effect of an imidazole derivative and BTA on copper in deionised water

Abstract

Purpose

The purpose of this paper is to study the inhibitive property of the mixture of an imidazole derivative (IMA) and benzotriazole (BTA) to the copper in deionised water.

Design/methodology/approach

Static mass‐loss tests, electrochemical tests and surface analysis are used to study the inhibitive property of the mixture of an IMA and BTA to copper in deionised water.

Findings

There is a synergistic inhibitive effect on inhibition of the copper by the IMA and BTA in deionised water, and the mixture of the IMA and BTA is an effective inhibitor that mainly hinders the anode reaction.

Practical implications

The mixture of the IMA and BTA is an effective inhibitor and can be used to prevent copper from corrosion in deionised water.

Originality/value

The mixture of the IMA and BTA is an effective inhibitor and should be suitable for use in the cooling water of an electricity generator unit to prevent corrosion of the copper conductors.
