The determination of corrosion inhibition activities of the compounds utilized Tafel plot method. Based on the analysis of Tafel plot data, there was linearity of each Langmuir isotherm adsorptions of each compound, which represent the monolayer formation of each compound on the carbon steel surface. The free Gibbs adsorption energy values, ΔG0ads, for Imidazole, compound 1, 2 and 3 are -28.01, -34.29, -31.68 and -33.26 kJ/mol, respectively, which indicated the spontaneity of adsorption process of each compound on carbon steel surface and also have the potent to interact with carbon steel through semi-physiosorption or semi-chemisorption. © UMIST 2004.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Corrosion inhibition activities,Imidazole,Langmuir isotherm adsorption,Microwave assisted organic synthesis,Tafel plot[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
