Abstract

This study examine the effectiveness of Nipah extract solutions to inhibit corrosion of aluminum (Al) in hydrochloric acid (HCl) media by using weight lost technique. Al's concentration in the inhibitor's solution is also detected by inductively coupled plasma (ICP-OES). Each part of Nipah palm consisting of frond (upper and lower), inflorescence stalk and husk was extracted by using wringer machine to provide the extract solution. The inhibition efficiency (% IE) of each solution was measured. The inhibition action of the extracts was discussed in view of Langmuir adsorption isotherm. It was found that the extracts act as a good corrosion inhibitor for Al in 2.0 M HCl solution. Weight loss of Al is decreased as the concentration of inhibitor is increased. Inhibition efficiency of Al corrosion was optimum in the presence of extract from inflorescence stalk which is 51.43 % (at higher concentration). The results obtained proved that extract solution from each part of Nipah palm can be serve as an effective inhibitor of Al in HCl media.
