Detection of Hydrogen Peroxide 1/5 – Introduction

Most electrochemical devices with low current (< 1 A) and potential ranges (< 10 V) are used for analytical methods. For many lab technicians quantitative analysis is an everyday task. Monitoring processes, product quality, etc. are tasks that are performed very often. There is always a demand for new methods or improvement of old ones because less time or fewer costs for a test to monitor processes or product quality will save a big amount of money. Catalyzed reactions are often important for these kinds of sensors, to make them selective and to make their power consumption low.

This series of articles aims to provide an introduction to electrochemical experiments. This series in particular deals with the detection of hydrogen peroxide with self-made Prussian Blue electrodes, and includes an experiment (PDF) you can carry out yourself. 


The goal of this series of articles and corresponding experiment is to teach you:

  • What is Prussian Blue?
  • Why are catalysts used for sensors?
  • How to deposit Prussian Blue?
  • What is a calibration curve?
  • How to make a calibration curve?
  • How to use a calibration curve for quantification?


Prussian Blue electrodes

The following articles will give you an introduction to the detection of Hydrogen with Selfmade Prussian Blue electrodes, and finally a PDF of the experiment which you can print and perform yourself!

Please note that teachers can request the answers to the question in the instructions, using
