Stability of aluminium in 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid and ethylene glycol mixtures
Source abstract
Abstract
Abstract The stability of electrochemically passivity aluminium has been investigated in mixtures of ethylene glycol, 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid, Na 2 B 4 O 7 .10H 2 O and NaH 2 PO 4 . The effects of (i) borax and sodium dihydrogen phosphate salts presence, (ii) water absorption and (iii) ethylene glycol content are studied by electrochemical impedance spectroscopy (EIS). The results show a decrease in the polarization resistance and an increase in the capacitance associated with the passive oxide dielectric properties with an increase in the water and/or ethylene glycol content in the mixtures. The presence of Na 2 B 4 O 7 .10H 2 O and NaH 2 PO 4 salts stabilize the oxide layer.
