Cyclic voltammetric studies of the redox behavior of iron(III)-vitamin B6 complex at carbon paste electrode

Spectrophotometric and cyclic voltammetric study of interaction of Fe(iii) with vitamin B3 and vitamin B6

“…But the increasing and decreasing rate of potential is very small. This behavior can be described by slower charge propagation, probably due to difference in solvation and or permeability (Shaikh et al 2006, Akhtar et al 2008.…”

“…This can be rationalized by considering the size of the diffusion layer and the time taken to record the scan. So, the redox system (electron transfer process) in Fe(III)-niacin complex is also diffusion controlled (Shaikh et al 2006, Akhtar et al 2008, Bard and Faulkner 1980. The plot 7(i) shows that with the increase of scan rate, the peak potential separation increases because the cathodic peak shifts towards negative potential and that of anodic towards positive potential.…”

“…3(i) it is clear that with increasing scan rate, the peak potential separation increases because the cathodic peak shifts towards negative potential and that of anodic towards positive potential. Here the cause is the effect of IR drop (Shaikh et al 2006) . Fig.…”

“…In a previous paper, the authors reported the cyclic voltammetric studies of Fe(III)-vitamin B 6 complex in HEPES buffer at carbon paste electrode (Shaikh et al 2006). Solid product of Fe-vit B 6 complex was isolated and then CV studies were carried out by dissolving it in HEPES buffer.…”

Preparation and Characterization of Toxic Metal Complexes of Nicotinamide and Nicotinic acid

“…Tryptophan is an amino acid, which is a provitamin of niacin. We have been doing research on metal B vitamin complexes for few years (Ehsan et al 2001, Shaikh et al 2006and Rahman et al 2011. The present work includes the preparation of complexes of some toxic metal with nicotinamide and nicotinic acid in solid phase and their characterization using different conventional methods and studies of their various properties in order to establish the nature of metal-vitamin B 3 interactions.…”
