Abstract
Carbon steel suffers from serious corrosion in NaCl solution, the development of effective inhibitor has become a hot issue. The corrosion inhibition performance of sodium lauryl ether sulfate (AES) and lauryl betaine (BS-12) and the mixture of the two inhibitors were studied using electrochemical and weight-loss methods. Results showed the corrosion inhibition efficiency order is AES + BS-12 > BS-12 > AES, the inhibition efficiency of the inhibitor increases with the increasing of concentration and the maximum inhibition efficiency is 95.9% in the solution with 200 mg L−1 AES + BS-12. Inhibitor can adsorb on Q235 surface through physical and chemical interactions and the adsorption obeys Langmuir isotherm. The migration of the corrosive ions to the metal is hindered and the metal is protected.
期刊介绍：
As the leading archival journal devoted exclusively to chemical kinetics, the International Journal of Chemical Kinetics publishes original research in gas phase, condensed phase, and polymer reaction kinetics, as well as biochemical and surface kinetics. The Journal seeks to be the primary archive for careful experimental measurements of reaction kinetics, in both simple and complex systems. The Journal also presents new developments in applied theoretical kinetics and publishes large kinetic models, and the algorithms and estimates used in these models. These include methods for handling the large reaction networks important in biochemistry, catalysis, and free radical chemistry. In addition, the Journal explores such topics as the quantitative relationships between molecular structure and chemical reactivity, organic/inorganic chemistry and reaction mechanisms, and the reactive chemistry at interfaces.
