Abstract

The cyclic voltammetry of magnesium ferrites (Mg1-xFe2O4) plays important role as a primary investigation in relation to its electrochemical properties. This investigation has been encountered with the study of cyclic voltammetry of metal dopant (Mn, Co and Ni) magnesium ferrites. The doped and undoped magnesium ferrites were synthesized by a sol gel method using polyvinyl alcohol and citric acid mixed and stirred at 80 °C for 5 h. The gel products were calcined at 500-900 °C. Anautolab PGSTAT 30 interface coupled with a processor using a general purpose electrochemical system (GPES) software was applied to present the cyclic voltammetry. The mixture of fabricated doped or undoped ferrites and poly(vinylidene fluoride) (PVDF) deposited on a screen printed carbon electrode (SPCE) as the working electrode was dipped into a mixture of phosphate buffer and ferricyanide solution in the electrochemical system. The cyclic voltammetry curves were recorded applying a scan rate of 0.02 V s-1.
