The Cottrell Experiment and Diffusion Limitation 3/3 – Electrochemical Double Layer

In this chapter the electrochemical double layer and its features are discussed. The electrochemical double layer acts as a capacitor and every change in the potential of the electrode will induce a capacitive charging current that is caused by physics not by a chemical reaction. This current decays exponentially. 

The Cottrell Experiment and Diffusion Limitation 2/3 – The Cottrell Experiment

In this chapter, we discuss the Cottrell experiment. During the Cottrell experiment a potential step across a redox potential is applied and the current caused by the electrochemical reaction is recorded. The current is controlled by diffusion.

Detection of Hydrogen Peroxide 5/5 – The Calibration Curve

This chapter explains how to prepare and use a calibration curve. 

Article

Detection of Hydrogen Peroxide 4/5 – with Prussian Blue

This chapter is part of the series ‘Detection of hydrogen peroxide with Prussian Blue’. This chapter delves deeper into the specifics of detecting hydrogen peroxide using Prussian Blue.

Article

Detection of Hydrogen Peroxide 3/5 – What is Prussian Blue?

Prussian Blue (PB) is a deep blue pigment that is hardly soluble in water, but little amounts that are dissolved or dispersed in watercolor the solution intensively blue. Small Prussian Blue particles dispersed in water have been used as the first modern synthetic color. It is also known as Berlin Blue or Turnbull’s Blue. The pigment is used for various paints (Paris Blue) or to make the blue color for blueprints.

Detection of Hydrogen Peroxide 2/5 – Why detect Hydrogen Peroxide?

In this chapter, we explain what hydrogen peroxide is and why we detect it. Hydrogen peroxide is the simplest peroxide (a compound with an oxygen-oxygen single bond). It is also a strong oxidizer. Due to its oxidizing properties, hydrogen peroxide is often used as a bleach or cleaning agent.

Article

Biosensor

A biosensor is a sensor exploiting a biomolecule and is used to measure the presence of a certain substance in a liquid. For example, the medical world uses biosensors to detect a virus in the blood or to measure glucose levels in blood. These are mainly point-of-care applications, where direct results are important.
