Dynamic impedance data for various carboxylic acids corrosion inhibition of aluminium in alkaline media (pH=11)

This dataset contains the results of Dynamic Electrochemical Impedance Spectroscopy (DEIS) carried out in galvanostatic mode under iDC=0, carried out in order to define the corrosion inhibition effect of various studied carboxylic acids: citric acid, malic acid, maleic acid, succinic acid, tartaric acid, carballylic acid, and serine. The experiment was set up with a peristaltic pump injecting the corrosion inhibitor to the corrosion cell, thus allowing to study the instantaneous changes of the impedance data with increasing carboxylic acid concentration (in the range 0-20 mM). The injection rate was 0.37 mL/min.
Each folder contains 600 separate impedance results, each obtained every 10 seconds of the exposure, as well as a tpi file with time, potential, and current data recorded throughout the experiment. Detailed experimental conditions and results are described in Electrochimica Acta article: 10.1016/j.electacta.2018.08.070
