Studies of the deposition of CaCO₃ on a stainless steel surface by a novel electrochemical technique

This paper describes the application of a novel electrochemical-based technique for the investigation of scale deposition directly on a metallic surface. The work, also involving conventional bulk chemistry, has comprised a comparison of scale control inhibition by polyacrylic acid on bulk precipitation and on deposition at an electrode surface. It has been shown that the new technique can monitor the influence of an inhibitor on scale deposition. Moreover the new experimental approach has provided evidence that the efficiency of inhibitors may be substantially different in relation to surface deposition and bulk precipitation. © 1999 Elsevier Science B.V.
