Abstract

Close
- A detailed study is presented on the leaking of two different 2-electron-transfer redox mediators from zirconium phosphate-modified carbon-paste electrodes. Two redox mediators commonly used in bioelectrochemistry, viz. methylene green and riboflavin, were adsorbed on zirconium phosphate and further integrated into carbon paste. Fast scan cyclic voltammetry and scanning electrochemical microscopy were used to characterize the leakage of these redox mediators at different pH conditions. It could be shown that an exposure to acidic pH-values significantly increased the rate of their leakage from the mediator-zirconium phosphate-modified carbon paste, whereas a tight adsorption was observed at neutral pH.
