Electrochemical kinetic study of amperometric hydrogen peroxide biosensor fabricated using SBR

Electrochemical Kinetic Assessment of Rose Tissue Immobilized Biosensor for the Determination of Hydrogen Peroxide

“…The standard reduction potential of water is -0.828 V and of ferricinium ion is +0.400 V in this system. It would be especially cogent if the tails of the reduction function of water and ferricinium would not have any influence over our experimental range of potential.So it is very important that the background currentFigure 1(a) bears no relation to the reduction of water and the mediator[22,23].The binder, CSMR, is a chemical mixture consisting of chlorosulphonation brought about by the Reed-Horn reaction[24]. Though each component of the rubber has not been elucidated, residual current appearing inFigure 1(a) can be viewed as the reduction current of unidentified components in CSMR, or as the double layer charging current, considering that the signal in the forward scan is somewhat analogous in linearity.…”
