ABSTRACT
This study examined the effects of specific aminoquinoline molecules on the inhibition of aluminium corrosion in hydrochloric acid, as well as the effects of the amino group substituent at positions 5, 6, and 8. Experimental measurements using weight loss, EIS, and PDP were conducted. Six aminoquinolines (6-AMQ), seven aminoquinolines (7-AMQ), and eight aminoquinolines (8-AMQ) were used in different mass and temperature conditions with varying HCl concentrations to aid in weight loss. These inhibitors' adsorption properties were discovered to be in line with the long-muir isotherm; physical and chemical processes were all important. Comparatively speaking, 7-aminoquinoline performance was superior to 6- and 8-chloroquinoline, as indicated by the corrosion rate (CR), mass loss, percentage inhibition efficiency.........
