Abstract: | Influence of the PH value on sodium diethylcarbamate as a corrosion inhibitor for copper In aqueous solutions down to PH values of 5.1, sodium diethylcarbamate has a very good inhibiting effect on the corrosion of electrolyte copper. In solutions with PH values below 5.1, however, the application of this inhibitor has the effect of greatly increasing the rate of copper corrosion. |
