Kohlrabi-Based Amperometric Biosensor for Hydrogen Peroxide Measurement

Abstract
Hydrogen peroxide was determined amperometrically in a steady-state arrangement by utilizing a kohlrabi - ferrocene based carbon paste electrode. A very short response time (2.6 seconds) and a relatively large usable pH range (5.0–7.4) were obtained. Several important hydrogen donors were studied as possible interferences.
