Q.EhsanRenata Limited, Plot 1, Milk Vita Road, Section-07, Mirpur, Dhaka, Department of Chemistry, University of Dhaka, Dhaka 1000, BangladeshDepartment of Chemistry, University of Dhaka, Dhaka 1000, BangladeshThe principal target of this study is to interact iron with two B-vitamins such as niacin and pyridoxine in hydrochloric acid buffer and was proved to be successful using three electrochemical techniques named cyclic voltammetry, chronoamperometry and chronocoulometry. Then using the same techniques, pH of maximum interaction was investigated. For Fe (II)-niacin interaction, pH of maximum interaction was 1.6 but for Fe (II)-pyridoxine interaction, it was 2.2. At the pH of maximum interaction, composition of maximum interaction was determined by cyclic voltammetry. The composition study showed that more than one species was formed in all the cases. Chronoamperometric study showed that after interaction, in both the cases, the spike heights are decreased signaling towards the decrease in the rate of electrolysis as well as successful interactions. In case of chronocoulometric study, it was found that after interaction, the charge at τ decreased and increased for Fe (II)-niacin and Fe (II)-pyridoxine interactions respectively. The plots Q vs t1/2 and Qr vs θ concludes that after interaction adsorption occur in all the cases.
